When sprayed, the nickel and aluminum exothermically react, forming a nickel aluminide intermetallic.
The following examples are given by way of illustration and not limitation:
EXAMPLE 1 Finely divided aluminum powder (325 mesh) was admixed with 20% by weight of nickel boron powder based on aluminum, consisting of a foundry alloy containing 18% by weight of boron and having a particle size between about l-20 microns. The powder blend was then admixed with a conventional phenolic varnish having approximately 10% solid contents so as to form a mixture having the consistency of heavy syrup and containing about 60% by weight of the metal particles. 100 grams of the varnish powder mixture is then added to about 900 grams of nickel powder having a size between about 200- 325 mesh and the two are thoroughly mixed, with the mixing continued until the varnish dries leaving a fairly free-flowing powder in which all of the nickel core particles are clad with a dry film which contains the aluminum particles and nickel boron particles. The powder is then warmed to about 250 F. to ensure complete drying. The powder is then screened and hand-milled to reduce the same to a 100 mesh powder. The end powder consists approximately of 5% aluminum, 1% nickel boron, the balance nickel. The powder is flame-sprayed on a mild am plate which has been surface cleaned by smooth grinding. The spraying is effected at a distance of 6 from the plate, using a powder type flame spray gun as described in US. Patent 2,961,335 of Nov. 22, 1960 and sold by Metco, Inc., of Westbury, N.Y., under the trade name Thermospray powder gun. The spraying is effected at a rate of 5 to 10 lbs. of powder per hour, using acetylene gas as the fuel, at a pressure of 10 lbs. p.s.i. gauge and a flow rate of cu. ft./hr., and oxygen as the oxidizing gas at a pressure of 12 lbs. p.s.i. gauge and a flow rate of cu. ft./hr. During the spraying very little smoke is generated and a coating layer is built up to a thickness of between .003" and .005. The coating is self-bonded, has excellent oxidation resistant characteristics even at high temperatures, and can be used as an intermediate bonding coat.
EXAMPLE 2 Example 1 was repeated except that three batches of powder were made up containing 3, 4 and 5% by weight of aluminum, respectively, each containing 1% by weight of nickel boron. Each of the powder batches was sprayed as described in Example 1 and the amount of smoke generated was determined on the basis of the amount of time it took for the smoke to fill a booth having a volume of 36 cu. ft. The bond strength of the coatings produced for each of the batches was also tested in the conventional manner by spraying on the end face of a mild steel rod of approximately 1" diameter, grinding the sprayed coating smooth, and cementing a second, similar rod to the ground steel and pulling the two rods apart in tension and determining the force necessary to lift the coating.
Table I below indicates the results:
4 EXAMPLE 3 Example 2 was repeated exactly except that in each case the flame spray powder was formed without the nickel boron. The results obtained are shown in Table II below:
TABLE II Aluminum Bond Smoke, time to fill Content Strength" 36 cu. ft. volume (percent) (p.s.i.) (see) These figures are averages of 6 or more tests.
EXAMPLE 4 Example 1 may be repeated, using in place of the nickel boron foundry alloy, nickel boron alloys containing from 5-95 and preferably 7-25 boron.

The invention is, therefore, only intended to be limited by the appended claims or their equivalents wherein I have endeavored to claim all inherent novelty.
