    Abstract: A method for manufacturing a sliding part for a hermetic compressor is disclosed. Since the abrasion resistance and corrosion resistance of the sliding part is increased, the energy consumption efficiency is improved and the performance of the compressor can be enhanced. In addition, since the manufacturing process is shortened, the production cost can be reduced and the manufacturing time can be reduced. Moreover, since the thickness change of the sliding part is minimized, the defective rate of the part size can be reduced and its quality can be improved.

    Abstract: This invention relates to a high temperature-resistant piston head. The piston head includes a first portion formed of a first material of heat-resistant steel alloy and the second portion is formed of a second a material of steel alloy that may be the same or may or different from the first material. The first and second portions are joined by a friction weld to form the assembled piston head. The heat-resistant steel alloy includes about 0.1 to about 0.5 wt % carbon, up to about 0.6 wt % manganese, about 4.0 to about 6.0 wt % chromium, about 0.45 to about 0.65 wt % molybdenum, up to about 0.5 wt % nickel and the balance iron and incidental impurities. In one form the second material includes about 0.30 to about 0.55 wt % carbon, about 0.4 to about 1.10 wt % manganese, about 0.40 to about 1.25 wt % chromium, about 0.15 to about 0.45 wt % molybdenum, up to about 0.4 wt % silicon, up to about 2 wt % Ni and greater than about 90 wt % iron.

    Abstract: A hardfacing for downhole progressing cavity pumps is disclosed as well as a method for producing same. The hardfacing consists of a metal carbide layer applied to the ferrous pump rotor body by way of plasma spraying and a top layer of metallic material having a lower hardness than the metal carbide. The metal carbide layer has a grainy surface with a plurality of peaks and intermediate depressions, the peaks being formed by metal carbide grains at the surface of the metal carbide layer. The thickness of the top layer is adjusted such that the depressions between the peaks of the metal carbide layer are completely filled thereby providing the rotor with a metal carbide hardfacing of significantly reduced surface roughness. In the process of the invention, the pump rotor, which may be provided with a molybdenum bonding layer, is plasma coated with the metal carbide and the resulting carbide layer is covered with the metallic material top layer. The top layer is polished either until the dimensions thereof are within the tolerances acceptable for the finished rotor or until a majority of the peaks of the carbide layer are exposed. The hardfacing significantly increases the service life of the rotor and stator of downhole progressing cavity pumps.

    Abstract translation: 公开了一种用于井下前进腔泵的硬化面及其制造方法。 表面硬化由通过等离子喷涂施加到铁水泵转子体上的金属碳化物层和具有比金属碳化物低的硬度的金属材料顶层组成。 金属碳化物层具有多个峰和中间凹陷的颗粒状表面，该峰由金属碳化物层表面的金属碳化物颗粒形成。 调整顶层的厚度，使得金属碳化物层的峰之间的凹陷被完全填充，从而为转子提供显着降低的表面粗糙度的金属碳化物表面硬化。 在本发明的方法中，可以设置有钼粘合层的泵转子被等离子体涂覆有金属碳化物，并且所得到的碳化物层被金属材料顶层覆盖。 抛光顶层，直到其尺寸在成品转子可接受的公差内，或直到碳化物层的大部分峰暴露。 表面硬化显着增加了井下前进腔泵的转子和定子的使用寿命。
