Method for application of Ti-B coating on the Alsub2/subOsub3/sub ceramic base, Ti-B coating applied on the Alsub2/subOsub3/sub ceramic base by this method, and ceramic products, preferably cutting tools based on Alsub2/subOsub3/sub covered by Ti-B coating

摘要

method of coating ti - b on the substrate ceramic al2o3 db ibad method is characterized by the fact that leads him in a vacuum, favourably ~ 10-4 pa, using two beam: insulin release unit and beam ion beam for a noble gas, preferably ar + energy of 10 kev to 15 kev (from 8 x 10 - 15 j to 2.40 x 10 - 15 (j), preferably 15 kev (2.40 x 10 - 15 (j), in this waythe insulin release unit beam ions heading for? of 65u00b0 to 67u00b0, beneficial? = 67u00b0, relative to the normal to the surface of the disc (3) with tib2 and booster beam ions is angle beta of 75u00b0 to 90 degrees, preferably beta = 90 degrees, to the surface of the substrate (4) in the form of the ceramic article.the ti - b marked on al2o3 ceramic substrate is characterized by the fact that consists of at least one layer of ti - b amorphous or crystalline amorficzno - construction, in which nanokrystality tib2 are surrounded by an amorphous warp and ti - b and share in the crystalline phase is from 20% to 90% by volume. tib2.ceramic products, especially cutting tools based on al2o3, coated ti - b by this. at least one layer of coating ti - b has an amorphous structure or amorficzno - crystal, in which nanokrystality tib2 are surrounded by an amorphous warp and ti - b and share in the crystalline phase is from 20% to 90% by volume. tib2.
