ABSTRACT:
Particles such as magnetic iron oxide capable of being magnetized are crushed to obtain minute magnetic particles each size of which is not larger than 10 .mu.m. The minute magnetic particles are mixed as they are dispersed with such a binding material as cobalt or nickel. Thermal spraying particles each size of which is not smaller than 10 .mu.m are obtained from the mixture. Then, the thermal spraying particles are sprayed upon such a member as a turbine shaft to form a magnetic film on the member with plasma spraying method.
