摘要： In the application of plasma spraying to a metal body, it is intended to attain reduction of spraying cost and improvement of working efficiency in roughening operation while maintaining anticorrosive effects. An adhesion strength of spray coating comparable to that obtained in the conventional combination of blast treatment and gas flame spraying can be realized even if roughening is conducted with the use of simple tools by performing in advance such a roughening treatment that the average roughness (Ra) of surface of thermal spray subject falls within the range of 2 to 10 μm with the use of a grinding tool and thereafter carrying out thermal spraying under such conditions that the average area of each of molten particles when molten particles of a thermal spray material have stuck to the surface of thermal spray subject falls within the range of 10000 to 100000 μm2. In the roughening by means of grinding tools, large-scale apparatus is not needed as different from the blast treatment, and portable small tools can be used in overhead location work at field repair. The scattering of powder resulting from grinding is slight so that the danger of environmental pollution is low.
摘要翻译：在将等离子喷涂应用于金属体时，旨在降低喷涂成本，提高粗糙化操作中的工作效率，同时保持防腐蚀效果。即使通过使用简单的工具进行粗糙化，也可以预先进行这样的粗糙化处理，使平均粗糙度（Ra）达到最大值，可以实现与喷砂处理和气体火焰喷涂的常规组合相当的喷涂涂层的粘合强度，使用研磨工具将热喷涂对象的表面落入2〜10微米的范围内，然后在热喷涂材料的熔融颗粒已经卡住的条件下进行热喷涂到热喷雾对象的表面落在10000〜100000mum的范围内。在磨削工具的粗糙化中，不需要与喷砂处理不同的大型设备，而便携式小型工具可用于现场维修中的架空定位工作。粉碎产生的粉末散落轻微，造成环境污染的危险性较小。
