Method and principle of vacuum metallisation by evaporation using a Joule effect of premixed elements for forming a homogeneous alloy layer on a substrate or a number of layers of the latter or of other elements in a single vacuum cycle

摘要

Improvement to vacuum metalisation by evaporation using a Joule effect of premixed elements to form, starting from a crucible and on a substrate, a homogeneous alloy, of thickness established according to the number of evaporations which are defined and performed during a cycle of evacuation of the evaporation tank or to create, using the same principle, successive layers of alloys and other components which form a thickness layered at will. This improvement is made to Patent Application 8809898 and its Certificate of Addition No. 8811556.
