categories.Naxau CVD can deposit coatings from 5 microns to 20 microns thick, using TiN, TiCN and \u03b1-alumina (Al2O3) to form monolayers or multilayers.The CVD deposition process is typically at 900\u00b0C or above, with a coating time of 10 hours, and is only for high temperature resistant substrates.<\/p>\n<\/p><span><\/div><\/header><ul class=\"csbox_pt\"  ><li style=\"border-bottom:1px
