在海洋环境中,船舶的内舱和舷外结构、平台和港工设施在潮差飞溅区及大气段均存在着严重的腐蚀问题,这些部位采用常规的涂层和阴极保护技术无法满足其长效防护的要求,喷涂金属防护涂层技术是目前国际上解决海洋环境长效防护问题的重要手段,目前常用的金属防护涂层多为电弧喷涂或火焰喷涂金属或合金涂层.由于传统热喷涂工艺制备的涂层存在孔隙率高、热应力大等缺陷,近年来随
In the marine environment, there are serious corrosion problems in the tidal range splash zone and the atmospheric zone for the inner and outer structures of ships, platforms and port facilities, which can not meet their long-term needs using conventional coating and cathodic protection techniques Effective protection requirements, spraying metal protective coating technology is currently the international community to solve long-term protection of the marine environment an important means of protection, the current commonly used metal protective coating mostly arc spraying or flame spraying metal or alloy coating due to the traditional thermal spraying The coating prepared by the process has the defects of high porosity, large thermal stress and the like, and has been developed in recent years
