    摘要: This invention relates to a composite mandrel and its processing technology, including: processing, connection, welding, alloy overlaying, tempering after overlaying, polishing, chrome plating etc., on the whole and auxiliary body of mandrel. The composite mandrel includes a plurality of main and auxiliary bodies, the surface is overlaid with high temperature resistant, wear resistant, thermal fatigue resistant alloy, polished, and chrome plated, obtaining the characteristics of wear resistance, thermal fatigue resistance and high temperature resistance. The whole process not only increase the strength, toughness and hardness of the mandrel, improves its service quality, but also prolong the service life. With simple structure and reliable quality, composite mandrel can meet the requirements of different running condition. Whether for new-made mandrels, or for equal diameter renewal of failed mandrels, composite mandrel process can show its advantages of suitable material quantity, energy saving, consumption reduction, and production cost reduction.

    摘要: A coated piston ring for a piston is provided. The piston ring includes a running surface, a flank surface, and a transition surface therebetween. The transition surface curves or extends at an angle between the running surface and the flank surface. A running layer is disposed over the running surface and over at least a portion of the transition surface. A flank layer is disposed over the flank surface and over at least a portion of the transition surface. The running layer is applied by physical vapor deposition, and the running layer is applied by galvanic deposition. The running layer is formed of chromium nitride, and the flank layer is formed of chromium. A portion of the flank layer overlaps and is disposed outward of a portion of the running layer. During operation of the piston, the overlapping portion is spaced from both the piston and the cylinder.

    摘要: The invention relates to a textile machine tool part (11) that is used in textile processing in a textile machine and to a method for producing same. The textile machine tool part (11) has a tool core (16) made of a core material and is coated, at least in part, with a wear-resistant coating. The wear-resistant coating (17) is applied to a core surface (18) that has a first microstructure (19). The first microstructure (19) is preferably created using electrochemical etching in the core surface (18). The wear-resistant coating (17) applied thereto is preferably applied directly to at least a section of the core surface (18) having the first microstructure (19) using electrochemical deposition and has a layer thickness of a maximum of 20 μm.

    摘要: A method for creating a chrome-plated surface having a matte finish that typically includes: controlling a resistance of a current bridge circuit; depositing a first chromium layer on a substrate positioned in a chromium bath, wherein the first chromium layer is deposited by supplying current from a power source that is electrically connected to the substrate and to anodes positioned in the chromium bath; etching the first chromium layer by engaging a current bridge that closes the current bridge circuit; depositing a first intermediate chromium layer, wherein the first intermediate chromium layer is deposited by supplying current from the power source; etching the first intermediate chromium layer, wherein the first intermediate chromium layer is etched by engaging the current bridge; and depositing a final chromium layer, wherein the final chromium layer is deposited by supplying current from the power source.
