Evaporation Coating Sources Have Three Varieties - Information - IKS PVD Expertise Shenyang Co. Ltd

(1) resistance heating supply: with refractory metals corresponding to tungsten, tantalum made of foil or filamate, by way of the current, heating within the above it or positioned within the crucible evaporating material, resistance heating source is primarily used for evaporation of Cd, Pb, Ag, Al, Cu, Cr, Au, Ni and different materials;

E-Beam or Electron Beam Evaporation is a type of Bodily Vapor Deposition through which the goal materials for use as a coating is bombarded with an electron beam from a charged tungsten filament to evaporate and convert it to a gaseous state for deposition on the fabric to be coated. Happening in a high vacuum chamber, these atoms or molecules in a vapor section then precipitate and kind a skinny film Multi Arc Ion Coating Equipment on the substrate.

Deposit the film at increased vacuum than what you are using at= present. For good adhesion, Degass the substrates before deposition. Make = barely thicker films. Anneal them after evaporation in vacuum at larger t= emperatures for getting rid of voids. See if you are able to resolve the prob= lem. Substrate cleaning can be improved for better uniformity. Good lu= ck.
