It was found that the sprayed coatings from pseudo-alloys 95Cr18—AD1\" and 06Cr19Ni9Ti—AD1 contain mainly α-Fe, which is due to alloying of steel particles in the process of spraying with aluminum. It is shown that coatings made of 95Cr18 and 06Cr19Ni9Ti steels have a higher wear resistance under dry friction conditions as compared to composite coatings. The reduced wear resistance of pseudo-alloys is associated with the presence of a large amount of relatively soft aluminum in them.

The microdeformation of copper decreases from 187 to 119 % with an increase in the deposition temperature and does not depend on the overlap coefficient.

Schemes involve intensive shifts between iron particles. One of the schemes is designed for forming billets, which after their sintering are deformed in dies without heating. The second of the schemes is designed for manufacturing directly at the stage of compacting the powder of conical thin-walled bushings of variable cross-section. As a result of the shifts between the particles, the densities of the molded billets were achieved, which allowed them to be tested for shear strength up to the sintering stage. The dependences between the density in the sections of the molded billet, its hardness and strength after sintering are experimentally determined. The dependence of the shear stress on the work piece on its molding scheme, the effect of magnetic pulse processing (MPP), and the powder composition is studied and described by the regression equation. The dependence of strength distribution in manufactured thin-walled bushings on the place of its measurement, the impact of MPP and powder composition is described similarly.","PeriodicalId":178558,"journal":{"name":"Strengthening Technologies and Coatings","volume":"295 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132305870","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
