Title:
PARTS FOR VACUUM FILM-FORMING DEVICE
Document Type and Number:
WIPO Patent Application WO/2001/048260
Kind Code:
A1
Abstract:
A part for a vacuum film-forming device which has a body thereof and a thermally sprayed coating, characterized in that the thermally sprayed coating has a roughness such that an average separation (S) between local mountaintops ranges 50 to 150 $g(m), and the maximum depth (Rv) of a valley and the maximum height (Rp) of a peak range 20 to 70 µm respectively; a target device comprising the thermally sprayed coating; and a vacuum film-forming device using the above part in a portion for holding a material to have a film formed thereon, a portion for holding a raw material of a film, a part for prevention of attaching, or the like. The thermally sprayed coating preferably comprises a low hardness coating selected from among an Al-based thermally sprayed coating having a Hv (Vickers hardness) of 30 or less, a Cu-based thermally sprayed coating having a Hv of 100 or less, a Ni-based thermally sprayed coating having a Hv of 200 or less, a Ti-based thermally sprayed coating having a Hv of 300 or less, a Mo-based thermally sprayed coating having a Hv of 300 or less and a W-based thermally sprayed coating having a Hv of 500 or less. The part for a vacuum film-forming device can be used for suppressing, effectively and stably, the exfoliation of the film-forming material attached onto the part during the process of film-forming and thus reducing the number of times for the cleaning of the device or the exchange of the part.
