The high velocity arc spraying technology and powder-cored metal threads were bi-used to repair the waste components, and the integration between coating preparation and materials formation to Fe-Al base intermetallic compounds came true. A new supersonic ion spraying technique, named bi-channel, bi-temperature, was invented to solve successfully the issues of over-melting, half-cooked and burned materials. The high-energy mechanical and chemical method with own property right was explored to solve successfully the issue, which the nano particles dispersed evenly and suspended stably in the solution. After perfecting the techniques the high-performance co-electrodeposition between the conductive matrixes metal Ni and the nonconductive nano particles carried out. The excellent nano anti-friction self-repairing additives was prepared to achieve elementarily the self-repairing on the worn surface during the equipment worked.
