The raw materials powder which becomes raw materials powder film canning manner and canning

摘要

PROBLEM TO BE SOLVED: To provide a method for covering a raw material powder film which forms a uniform film with a reduced surface roughness (maximum height) on an object.;SOLUTION: An object 4 to be covered with a film, balls 3 having a fine diameter and raw material powder 2 formed into a film are packed into a vessel 1 at a packing ratio of ≥80%, then are subjected to mechanical alloying treatment, and thus a covering film by friction of high energy can be formed as a uniform film on the surface of the object 4.;COPYRIGHT: (C)2010,JPO&INPIT
