| Abstract: |
| With the implementation of the strategy “establishing a maritime power”, developing marine equipment and building marine engineering have become vital part of promoting and implementing national maritime strategy. In view of the fact that marine equipment continually serves in ocean environment, corrosion damage of marine engineering materials has become a key problem. In particular, moving parts in marine equipment, such as seawater pumps, valves, seawater hydraulic transmission systems, underwater operation robot arm, deep sea exploration and exploitation equipment, are subject to coupled damage of corrosive wear. Hence, allowing for corrosive wear failure behavior and mechanism of typical metallic materials, the effects of service conditions, corrosive medium, electrochemical and material factors on corrosive wear properties of typical metallic materials (stainless steel, titanium alloy, aluminum alloy, nickel alloy, etc.) in seawater were reviewed. The relationship between service conditions, corrosive medium concentration, pH value, applied potential and material factors was analyzed comprehensively. The corrosion, wear and their interaction during corrosive wear process of metallic materials were expounded. A series of integrated anti-wear & anti-corrosion coating technologies, such as corrosive wear properties and typical application of PVD coating, thermal spraying coating, electroplating coating and polymer bonding coating were compared on this basis. Mechanism of optimizing corrosive wear properties with the integrative protective material was analyzed, so as to provide helpful enlightenment for resolving corrosive wear problems of metallic materials. |
