摘要： A structural component made of a base metal composition on a nickel or cobalt basis is provided with a protective coating against oxidation, corrosion, and thermal fatigue. The protective coating and the base metal are made of chemically the same or identical material, whereby the bonding of the protective coating is increased, the tendency to crack is reduced, and the resistance to thermal fatigue is improved. The grain size of the coating is substantially smaller than the grain size of the base metal composition.

摘要： Preparation of feed screw having a wear resistant alloy coating thereon for the injection molding or extrusion of plastic. Nickel-based alloys that have shown themselves to be compatible with inlaid barrel liners by virtue of similar wear ratios, modulus of elasticity, ultimate yield strength, and linear thermal coefficients of expansion, are sprayed at high velocity onto a heated feed screw to mechanically bond the alloy to the feed screw. The alloy is then fused to the feed screw in a controlled manner. Following the fusing process, the feed screw and alloy thereon is heated and allowed to cool in a highly controlled environment to produce a crack-free dense coating of the alloy on the screw substrate.

摘要： A method of altering the crystal form of an alloy is disclosed. To accomplish this change in crystal form, the concentrations of the more volatile constituents of the alloy are reduced and the concentration of the less volatile constituents is increased on a relative basis. The process may be carried out in forming a reinforced structure. For this purpose, an improved reinforced matrix and a method of forming it are taught. The reinforcement may be silicon carbide filaments or other reinforcing filaments. The matrix is a titanium 1421 alloy nominally containing 14 weight percent of aluminum and 21 weight percent of niobium. The matrix is formed by plasma-spray forming a powder of the alloy to impart to the alloy particles a superheat during the plasma-spraying as the particles traverse the plasma plume. As a result of the superheat, the alloy is changed in its composition to reduce the aluminum concentration and to increase the niobium and titanium concentrations on a relative basis. As a result of the change in composition the crystal form of the spray deposited matrix is altered to increase the amount of the beta-phase crystal form of the alloy which is present and to decrease the amount of the alpha-2 crystal form of the alloy which is present. The result is the formation of a matrix which is less subject to cracking and which has greater strength.

摘要： Leakproof, adhesive, non-lamellar and pore-free antifriction coatings can be produced from essentially oxidation-sensitive dispersion alloys, with at least two metallic alloy components forming a miscibility gap in the solid state, by means of vacuum plasma-spraying with a practically homogeneous material distribution. Precipitation crystallites of alloy components are significantly below 5 .mu.m and fringe-crystal growth is definitely inhibited. By adding hard particles during the coating process further dispersion consolidation can be achieved. Such antifriction coatings improve longevity, corrosion resistance and emergency lubrication of sliding surfaces without reducing their running-in characteristics and their ability to bed in foreign matter. They can be deposited individually on to sliding bearing components or continuously on to supporting strips.

摘要： In order to accommodate post-manufacturing, or secondary operations in precision assemblies using composite materials, where the secondary operations consist of drilling, machining, grinding, lapping, or other material-removing processing, without the need to resort to expensive diamond tooling and while maintaining needed structural integrity, a composite formed of a base material, a matrix, and a machineable material is provided. The matrix is bonded to the base material and the machineable material is rendered integral with the matrix and sufficiently thick to accommodate subsequent material-removing processing to a precision dimension. By utilizing the composite, method of forming the composite, and article of manufacture, it is possible to take advantage of the characteristics of high strength and light weight even in precision assemblies due to the fact that the machineable surface is not required for structural integrity, and the machineable surface can be applied for initial machining or other material-removing processing and reapplied for subsequent machining or other material-removing processing to restore worn or damaged surfaces.
