Abstract
Abstract An alloy of nickel and aluminum, which also may contain varying percentages of intermetallics, in the form of a wire or rod is sprayed in an electric arc spray gun to form a self-bonding coating on a smooth, clean substrate. Alternatively an alloy of nickel and titanium, which also may contain varying percentages of intermetallics, in the form of a wire may be similarly electric arc sprayed to effect a self-bonding coating on a substrate. The nickel aluminum alloy and possibly intermetallics or the nickel titanium alloy and possibly intermetallics are supplied as a wire feed to the electric arc spray gun, and when heated in the electric arc of the spray gun and sprayed onto a substrate will form a coating that has a high degree of tenacity to many metal substrates and also has a moderate degree of hardness, low Rc, high Rb. The self-bonding is attributed to the formation of superheated liquid in the arc process and the affinity of that superheated liquid to iron, nickel, aluminum, etc.

Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
75 words
A method of thermal spraying a substrate to deposit a self-bonding coating on such substrate, comprising supplying an electric arc thermal spray gun with a wire feed comprising an alloy of nickel and aluminum or titanium, and using such electric arc thermal spray gun, spraying said wire feed onto such substrate to coat the same thereby to establish a diffusion bond between such coating and such substrate to provide a self-bonding coating on such substrate.
Claim 2
Independent Claim
75 words
A method of thermal spraying a substrate to deposit a self-bonding coating on such substrate, comprising supplying an electric arc thermal spray gun with a wire feed comprising an alloy of nickel and aluminum or titanium, and using such electric arc thermal spray gun, spraying said wire feed onto such substrate to coat the same thereby to establish a diffusion bond between such coating and such substrate to provide a self-bonding coating on such substrate.
