I. Introduction

As an important component of acoustic equipment, acoustic tubes are widely used in numerous fields such as oil exploration, geological surveys, marine monitoring, and building structure inspection. In these applications, acoustic tubes need to withstand various harsh environmental conditions, such as high pressure, high temperature, highly corrosive media, and mechanical wear. Therefore, the performance and reliability of acoustic tubes are crucial, and the selection of materials and coatings is a key factor determining their performance and lifespan.

Traditional acoustic tube materials and coatings are gradually revealing many limitations when facing increasingly complex and demanding application environments. For example, some metallic materials are prone to corrosion, leading to a decline in the performance of the acoustic tube or even its failure; while ordinary coatings may experience peeling and wear after long-term use, failing to effectively protect the acoustic tube. To overcome these challenges, researchers and engineers are constantly exploring new materials and coating technologies, driving continuous progress in the field of acoustic tube materials and coatings.

II. Recent Advances in Acoustic Tube Materials

(I) High-Strength Alloys

High-strength alloys play a crucial role in acoustic tube manufacturing. Traditional metal acoustic tubes are typically made of steel, but steel has limitations in terms of strength, corrosion resistance, and weight. In recent years, the emergence of a series of new high-strength alloys has brought new opportunities for improving acoustic tube performance.

For example, titanium alloys possess characteristics such as high strength, low density, good corrosion resistance, and excellent mechanical properties. In acoustic tube applications, titanium alloy acoustic tubes can withstand higher pressure and tension while reducing the overall weight of the tube, facilitating transportation and installation. Furthermore, titanium alloys have excellent corrosion resistance in marine environments, effectively resisting seawater erosion and extending the service life of the acoustic tube in fields such as marine monitoring.

Another high-strength alloy that has attracted considerable attention is nickel-based alloys. Nickel-based alloys possess excellent high-temperature strength and oxidation resistance, making them suitable for acoustic tube applications in high-temperature environments. In some oil exploration and geological survey projects, the high-temperature environment deep underground places extremely high demands on acoustic tubes. Nickel-based alloy acoustic tubes can maintain stable performance under high-temperature conditions, ensuring accurate transmission of acoustic signals.

(II) Corrosion-Resistant Polymers

Besides metallic materials, corrosion-resistant polymers are increasingly widely used in the acoustic tube field. Polymer materials have advantages such as light weight, low cost, and good corrosion resistance, meeting the needs of applications that are sensitive to weight and cost.

Polyethylene (PE) is a common corrosion-resistant polymer with good chemical stability and flexibility. PE acoustic tubes can be used in scenarios such as underground pipeline inspection and marine environmental monitoring, where their corrosion resistance effectively prevents erosion by chemicals and seawater. Furthermore, PE materials can be further modified to improve their performance; for example, adding reinforcing fibers can improve their strength and stiffness.

Polytetrafluoroethylene (PTFE) is also a high-performance corrosion-resistant polymer with an extremely low coefficient of friction and excellent chemical inertness. PTFE coating can be applied to the surface of metal acoustic tubes to form a protective film, effectively preventing corrosion and wear. Simultaneously, the PTFE coating reduces friction between the acoustic tube and the surrounding medium, improving the transmission efficiency of acoustic signals.

(III) Composite Materials

Composite materials are novel materials composed of two or more materials with different properties, exhibiting excellent comprehensive performance. In acoustic tube manufacturing, the application of composite materials can fully leverage the advantages of different materials, optimizing the performance of the acoustic tube.

For example, glass fiber reinforced plastic (GFRP) is a common composite material, composed of glass fiber and a resin matrix. GFRP acoustic tubes have advantages such as light weight, high strength, and good corrosion resistance, making them suitable for applications with high requirements for weight and corrosion resistance. Compared to metal acoustic tubes, GFRP acoustic tubes are more convenient to transport and install, while also reducing overall costs.

Carbon fiber reinforced plastic (CFRP) has higher strength and stiffness, as well as good electrical and thermal conductivity. CFRP acoustic tubes show great potential in high-end applications such as aerospace and precision instrument testing. Its high strength and lightweight characteristics meet the stringent performance requirements of these fields for sound tubes.

III. Innovative Coating Technologies

(I) Nanocoatings

Nanocoatings represent a significant breakthrough in coating technology in recent years. Nanomaterials possess unique physical and chemical properties, such as high specific surface area, excellent mechanical properties, and chemical stability. Applying nanomaterials to sound tube coatings can significantly improve coating performance.

Nano-ceramic coatings possess extremely high hardness and wear resistance, effectively protecting the sound tube surface from mechanical wear and scratches. Simultaneously, nano-ceramic coatings also exhibit good corrosion resistance, resisting the erosion of various chemical media. In harsh industrial environments, nano-ceramic coatings can extend the service life of sound tubes and reduce maintenance costs.

Nano-polymer coatings possess excellent flexibility and adhesion, tightly adhering to the sound tube surface to form a uniform protective film. Nano-polymer coatings can also be further enhanced by adding functional nanoparticles, such as antibacterial nanoparticles and self-healing nanoparticles, to endow sound tubes with even more special functions. For example, antibacterial nano-coatings can inhibit bacterial growth on the surface of the acoustic tube, making them suitable for applications with high hygiene requirements; self-healing nano-coatings can automatically repair themselves when micro-cracks appear, maintaining the integrity of the coating.

(II) Multifunctional Composite Coatings

Multifunctional composite coatings combine multiple coating materials with different functions to form a coating system with multiple properties. This type of coating can simultaneously meet the various needs of the acoustic tube under different environmental conditions, improving the overall performance of the acoustic tube.

For example, a multifunctional composite coating can consist of an anti-corrosion coating, a wear-resistant coating, and a heat-insulating coating. The anti-corrosion coating effectively prevents the acoustic tube from being chemically corroded; the wear-resistant coating enhances the wear resistance of the acoustic tube surface and reduces mechanical wear; the heat-insulating coating reduces the temperature of the acoustic tube in high-temperature environments, protecting the electronic components and acoustic sensors inside the acoustic tube. Through the application of this multifunctional composite coating, the acoustic tube can operate stably in complex environments, improving its reliability and service life.

(III) Intelligent Coatings

Intelligent coatings are a new type of coating that can sense environmental changes and respond accordingly. Smart coatings typically comprise sensors, actuators, and smart materials, enabling real-time monitoring of the sound tube's operating status and environmental parameters, and automatically adjusting the coating's performance based on the monitoring results.

For example, a self-sensing smart coating can monitor parameters such as stress, strain, and temperature on the sound tube surface in real time. When the sound tube is subjected to excessive stress or temperature changes, the smart coating can promptly issue an alarm, reminding operators to take appropriate measures to prevent damage. Furthermore, the smart coating can automatically adjust its corrosion resistance and wear resistance properties according to environmental changes, achieving adaptive protection.
