Patent ID: 6861089

Claim:
A method of inhibiting production of projections in a metal deposited-film characterized by using a vapor deposition apparatus comprising, in a vacuum-treating chamber, an evaporating section for a depositing material, and an accommodating member and/or a holding member for accommodation and/or hold of work pieces, respectively, and, in depositing a metal depositing material on each of the surface of said work pieces with said accommodating member and/or said holding member being made rotated about the horizontal rotational axis thereof, carrying out vapor deposition with a Vickers hardness of a film formed on each of the surface of said work pieces maintained at 25 or more. said accommodating member and/or a holding member for accommodation and/or hold of work pieces is a tubular barrel for accommodation of said work pieces, said tubular barrel is formed of a mesh net having an open area ratio of 50 to 85%, said tubular barrel is revolvably supported circumferentially outside a horizontal rotational axis of a support member made rotatable about the rotational axis, for revolution about the rotational axis of said support member by rotating said support member, said tubular barrel revolves about the rotational axis of said support member, whereby vapor deposition is carried out under a condition that said work pieces collide with and rub against one another in said tubular barrel, a plurality of said tubular barrels are supported in an annular shape circumferentially outside the rotational axis of said support member, and said work piece is a rare earth metal-based permanent magnet.
