Evaluating the Applicability of Electrodeformation Placing Technology by a Flexible Tool for Chromeing Hydrocilindes
Source abstract
Abstract
Abstract—The results of comparative triboengineering tests of chromium coatings formed using electroplating deposition and electrodeformation cladding with a flexible tool (EDCFT) are given in this work. In the formation of coatings by the EDCFT method, sintered bars of chromium powder doped with additives of ultradispersed diamond graphite mixture (UDGM) and thermally expanded graphite were used as coating materials (donors). It has been established that, when rubbing without a lubricant, sprays of rubber on the surface of specimens with a coating with the lowest values of the coefficient of sliding friction fsl and total weight wear Δm have samples with chromium coatings formed by electroplating (ftr = 0.37, Δm = 0.2 × ten–3 d) using the EDCFT method from a donor doped with the ultradispersed diamond-graphite mixture UDGM (ftr = 0.35, Δm = 0.23 × ten–3 d). Bench tests of hydraulic cylinders with full-scale stock samples with a coating formed by the EDCFT method from chromium doped with UDGM have established full compliance of the prototypes of hydraulic cylinders with the specifications.
