Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
113 words
As an article of manufacture, a composite wire adapted for flame spraying consisting essentially of a particulate material selected from the group consisting of molybdenum, boron, tantalum, tungsten, tungsten carbide, silicon carbide, alumina, zirconia, oxides of chrome, titania, alloys of nickel and chromium with iron, and mixtures of these, said material having a particle size smaller than 80-mesh in an admixture with a mixture of a thermoplastic resin and a phenolic resin in a cured state wherein said material comprises from about 75 percent to about 971/2 percent by weight of total composite with the balance being said phenolic resin and thermoplastic resin in a ratio to each other of 4:1 to 1:9.
Claim 2
Dependent Claim
