摘要： A method for depositing a thick, adherent and coherent polycrystalline diamond (PCD) film onto a metallic substrate using a deposition rate of no greater than 0.4 .mu.m per hour. The resulting PCD Film has a smooth surface finish, enhanced crystal orientation in comparision to industrial grade diamond powder particularly in the (220) and (400) directions, and excellent electrical and thermal properties. The method enables one to deposit PCD films having a thickness of at least 12 microns for applications on flat as well as curved substrates having wide use in the electronics industry. Thick PCD films of this invention have been found to be ideal for dissipating heat from radio frequency (RF) and microwave (MW) devices.

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.
摘要翻译：公开了一种改进的高侵蚀性和磨蚀性耐磨多层涂层系统，其在基板上提供防止大颗粒冲击的保护，其包括多个复合层。在每个复合层中，最靠近基底的第一层包括足够厚度的钨，以赋予涂层体系显着的侵蚀和磨损耐磨特性，而沉积在第一层上的第二层包括钨和碳化钨的混合物，以及碳化钨包括W2C，W3C或两者的混合物。由于所得到的涂层体系在衬底上具有增强的高循环疲劳强度，所以涂覆系统在诸如涡轮机叶片和类似的制品之类的结构中是特别有用的，其中在正常操作期间发生如此高的应力循环。制备这种改进的复合涂层体系的方法也是一个缺点。

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 process is described for the solvent refining of coal into a gas product, a liquid product and a normally solid dissolved product. Particulate coal and a unique co-catalyst system are suspended in a coal solvent and processed in a coal liquefaction reactor, preferably an ebullated bed reactor. The co-catalyst system comprises a combination of a stoichiometric excess of iron oxide and pyrite which reduce predominantly to active iron sulfide catalysts in the reaction zone. This catalyst system results in increased catalytic activity with attendant improved coal conversion and enhanced oil product distribution as well as reduced sulfide effluent. Iron oxide is used in a stoichiometric excess of that required to react with sulfur indigenous to the feed coal and that produced during reduction of the pyrite catalyst to iron sulfide.
