Expanding human activity space and better utilizing natural resources are always being the continuous driving forces for the development of human society. With the great development of engineering technologies for last two centuries, we humans can set foot on the moon and reach to areas (deep space, deep sea, and polar region etc.) where might have not been touched by intelligence life. Such areas generally, have extreme harsh service conditions for components (high service temperature, high stress level, extreme corrosive environments, high radiation level etc.) which keep challenging the engineering technologies. Usually, a single material cannot meet all the service requirements. Therefore, a reasonable and practical solution is to apply a protective coating on the surface of mechanical components to increase the performances (the corrosion/erosion resistance, tribology performance and thermal isolation). Coating technologies play a more and more important role on meeting the service requirements in harsh environments.
At harsh service environments, single material usually cannot meet all the service requirements. Furthermore, the materials face significant degradation to perform its task in service as a result of environmental expose. Failures often happen in the form of corrosion, oxidation, erosion, wear and mechanical fracture. Coating technology has proved to be an effective method of inhibiting surface failure in different environments, and is also being successfully applied in a large number of equipment. While the performance of protecting coatings would definitely change when the service environments go to hash, which might possesses the higher temperature, the higher pressure, more complex chemical combinations and so on. For example, the traditional YSZ-based thermal barrier coatings cannot reliably serve at temperatures above 1473 K for long-term service. The typical MoS2-based solid lubricating coatings would break down in high humidity environments. The common organic anti-corrosion coating would delaminate under high hydrostatic pressure. Therefore, the main purpose of this topic is to explore coating materials with excellent protective function under harsh environments, providing technical support for the development of high-end equipment in more extreme condition.
The scope of this topic is specifically focused on the coating technologies which are developed to improve performance of mechanical components serving in harsh environments. The harsh environments mean environments with different and more extreme characteristics in comparison with normal environments such as high temperature, high pressure, high speed, complex chemical combinations, etc. The performance and mechanism of protective coatings, the design and fabrication of advances coatings, the application and effect of new coatings in different harsh environments are welcome. Subtopics of coating technologies include, but are not limited to, the following:
• Electrochemical deposition
• Chemical vapor deposition
• Physical vapor deposition
• Ion Implantation
• Thermal spraying
• Heat treatment
