摘要： An improved capacitively coupled radio frequency-plasma enhanced chemical vapor deposition (PECVD) apparatus and process are disclosed for depositing a uniform coating of material on substrates. The apparatus includes a secondary electrode defining a reaction zone within an outer chamber and an RF electrode in concert with the secondary electrode for generating a plasma within the reaction zone. The electrode comprising a base and a finger extending through the reaction zone for distributing a plasma field uniformly throughout the reaction zone. The process comprises heating a substrate to a deposition temperature in the range of about 300.degree. to 650.degree. C. Reactant gases are introduced into the PECVD reactor and a coating of about 0.2 to about 20 .mu.m is deposited onto the heated substrate. This low temperature process is particularly adapted to coating three-dimensional objects of metals, metal alloys and mixtures of metals.

摘要： An improved highly erosive and abrasive wear resistant multi-layered coating system on a substrate which provides protection against impact of large particles is disclosed comprising a plurality of composite layers. In each of the composite layers, the first layer closest to the substrate comprises tungsten of sufficient thickness to confer substantial erosion and abrasion wear resistance characteristics to the coating system and a second layer deposited on the first layer comprises a mixture of tungsten and tungsten carbide and the tungsten carbide comprises W.sub.2 C, W.sub.3 C, or a mixture of both. Because the resulting coating system has enhanced high cycle fatigue strength over the substrate, the coating system is especially useful on such structures as turbine blades and similar articles of manufacture where such high stress cycles occur during normal operation. Also dislcosed is the method for preparing such improved composite coating systems.

摘要： Extremely hard, fine grained tungsten/carbon alloys are described which are produced by thermochemical deposition. The alloys consist primarily of a mixture of a substantially pure tungsten phase and at least one carbide phase wherein the carbide phase consists of W.sub.2 C or W.sub.3 C or a mixture of W.sub.2 C and W.sub.3 C. The disclosed tungsten/carbon alloys are free of columnar grains and consist essentially of extremely fine, equiaxial crystals. Also disclosed is a method of producing the disclosed material.

摘要： "A coated substrate product is described wherein the outer coating on the substrate is comprised of a chemically vapor deposited and heat treated mixture of tungsten and tungsten carbide. The tungsten carbide phase consists of W.sub.2 C or W.sub.3 C or a mixture of W.sub.2 C and W.sub.3 C. During the heat treating, the coated substrate is heated to the deposition temperature or not substantially above the deposition temperature in a non-reactive atmosphere. The heat treating temperature is sufficient to confer a desired improvement in erosive and abrasive wear resistance in the outer coating but does not result in substantial degradation of the mechanical properties of the substrate or in formation of undesirable inter-metallic layers".

摘要： A Fischer-Tropsch process utilizing a product selective and stable catalyst by which synthesis gas, particularly carbon-monoxide rich synthesis gas is selectively converted to higher hydrocarbons of relatively narrow carbon number range is disclosed. In general, the selective and notably stable catalyst, consist of an inert carrier first treated with a Group IV B metal compound (such as zirconium or titanium), preferably an alkoxide compound, and subsequently treated with an organic compound of a Fischer-Tropsch metal catalyst, such as cobalt, iron or ruthenium carbonyl. Reactions with air and water and calcination are specifically avoided in the catalyst preparation procedure.
