    Abstract: A refrigerant compressor includes a compression unit having a roller and a vane for compressing refrigerant. The vane has a film having first to fourth layers on its metallic base member. The first layer is made of chromium. The second layer is made of chromium and tungsten-carbide. The third layer is made of metal-containing amorphous-carbon containing at least tungsten or tungsten-carbide. The fourth layer is made of non-metal-containing amorphous-carbon containing carbon and hydrogen. In the second layer, chromium content-rate on a first-layer side is larger than on a third-layer side, and tungsten-carbide content-rate on the third-layer side is larger than on the first-layer side. In the third layer, content-rate of the at least tungsten or tungsten-carbide on a second-layer side is larger than on a fourth-layer side. The roller with which an end-edge of the vane slidably-contacts is made of flake graphite cast iron containing molybdenum, nickel and chromium.

    Abstract: The invention relates to a two-part piston (1) for an internal combustion engine, consisting of an upper part (2) and a lower part (3) which is screwed to the upper part. The upper part (2) and the lower part (3) are in contact with each other, partially by means of inner bearing surfaces (25, 26) defining the lower side of an upper ring rib (10) and the upper side of a lower ring rib (11), and partially by means of outer bearing surfaces (28, 29) defining the lower side of the ring wall (9) and the upper side of a collar (27) applied to the lower part (29). In order to avoid frictional rubbing, frictional heat sealing and pressure-related material heat sealing, at least one of the bearing surfaces (25, 26, 28, 29) is easily and economically provided with a chrome layer (30) which has a structured surface comprising a plurality of raised parts and recesses.

    Abstract: Chromium nitride coating of machine components such as reciprocating pump plungers for continuous sliding contact with non-metallic packing and gasket materials greatly increases the performance life of fluid seals. In an air driven reciprocating constant pressure pump, exterior surfaces of the pump plunger are coated with chromium nitride to a thickness of seven to ten microns. The coating resists failure from repeated sliding contact against non-metallic packing and gasket materials for at least four million pump cycles, with no evidence of cracking or release of metallic particles which would embed in the packing or gasket material and score the plunger. In lower pressure pumps, interior walls of a housing against which a sliding gasket bears, when coated with chromium nitride, greatly increase the seal life of the sliding gasket.

    Abstract translation: 用于与非金属填料和衬垫材料连续滑动接触的往复式泵柱塞等机械部件的氮化铬涂层大大增加了流体密封件的使用寿命。 在空气驱动的往复式恒压泵中，泵柱塞的外表面涂覆有氮化铬，厚度为7至10微米。 该涂层可抵抗非金属填料和垫片材料反复滑动接触至少四百万泵循环的故障，没有任何迹象表明会嵌入填料或垫圈材料中的金属颗粒的破裂或释放，并使柱塞得分。 在低压泵中，当涂覆有氮化铬时，滑动垫圈承受的外壳的内壁大大增加了滑动垫圈的密封寿命。
