  • Patent number: 8821701
    Abstract: A target for use in an ion beam sputtering apparatus made of at least two target tiles where at least two of the target tiles are made of different chemical compositions and are mounted on a main tile and geometrically arranged on the main tile to yield a desired chemical composition on a sputtered substrate. In an alternate embodiment, the tiles are of varied thickness according to the desired chemical properties of the sputtered film. In yet another alternate embodiment, the target is comprised of plugs pressed in a green state which are disposed in cavities formed in a main tile also formed in a green state and the assembly can then be compacted and then sintered.
    Type: Grant

  • Publication number: 20100173172
    Abstract: A method of forming a wear-resistant coating on a metal substrate includes depositing a metal alloy onto the metal substrate to form a cladding, rough finishing the cladding to thereby provide the cladding with an average roughness, Ra, of from about 50 micro-inches to about 150 micro-inches, and work hardening the cladding to thereby form the wear-resistant coating and a hardened zone thereof, wherein the hardened zone has a hardness greater than a hardness of the metal substrate. A wear-resistant coating system includes the metal substrate and the wear-resistant coating disposed on the metal substrate. The wear-resistant coating is substantially resistant to corrosion from sea water at an ambient temperature of from about ?40° C. to about 50° C.
