Title: Member for precision equipment
Inventor: NAKAYAMA HIDEMI
IPC: B32B5/00
Filed: 1997-10-20
Abstract: PROBLEM TO BE SOLVED: To make the member light in weight, high in precision and improved in characteristics such as rigidity by providing the surface of the member consisting of a carbon fiber-reinforced composite member with ceramics coating film or metallic plating film of specified thickness. SOLUTION: As for carbon fiber-reinforced composite member, vibration damping is excellent and strength, dimensional precision, lightening, low thermal expansibility, precision workability or the like is tolerable, but wear resistance and mirror finishing properties are insufficient. Therefore, the surface of the member is coated with ceramics coating film or metallic plating film or an adhesive layer of a ceramics sintered body or a vapor-deposited layer of a ceramics sintered body. Moreover, the surface thereof is coated with ordinary metallic plating film by about <=1 mm, by which electrification of about 100% can be prevented. Furthermore, in the case ceramics members such as alumina, sialon, SiC or the like are used as the base for the member, the surface is preferably coated with thin coating film consisting of a carbon fiber composite member of <=1 mm.
