摘要： Advanced machine tool coatings for Ti machining are presented. The coatings of the present invention provide for protection from chemical reactivity and higher cutting temperatures. In accordance with one embodiment of the present invention, a coated machine tool is provided including a relatively hard underlayer and a chemically inert overlayer. The relatively hard underlayer is formed over the base material of the machine tool. The overlayer is formed over the underlayer, is chemically inert with respect to titanium, and comprises an oxide of yttrium or another metal oxide. In accordance with another embodiment of the present invention, a coated machine tool is provided including an alkaline earth metal fluoride overlayer that is substantially chemically inert with respect to titanium. The overlayer includes a metal intermixed with the metal fluoride. The intermixed metal is softer than the base material.

摘要： A method of providing corrosion resistant substrates having an amorphous metallic alloy coating thereon. The method comprises depositing refractory and transition elements, such as Ni, Nb, Ti and Cr, onto the substrate to provide a crystalline metallic layer thereon which is then irradiated to convert the layer into an amorphous metallic coating on the substrate. The coated substrate displays a corrosion resistance which is at least about four orders of magnitude greater than for the uncoated substrate in both lN HNO.sub.3 and 0.1 N NaCl aqueous solutions.
