One of the representatives of protective coatings are fire coatings based on Al and Al-Si, which have been used, among others, in the automotive industry. The production of Al-Si coatings using the fire method (known as: immersion) consists in immersing a previously degreased detail in a bath of molten coating metal. Al-Si coatings are applied permanently, and the connection between the coating and the substrate is ensured by the mutual diffusion of aluminum and iron, which leads to the formation of intermetallic phases. The study examines Al-Si coatings used in the automotive industry. The research included assessment of coatings in terms of structure, hardness distribution of elements, and surface condition (roughness). The chemical composition of the coatings was determined using EDX microanalysis and phase composition by diffractometric analysis. The final assessment focused on the impact of bending on the quality of the connection between the substrate and the coating.\u0000\u0000","PeriodicalId":348539,"journal":{"name":"Inżynieria Powierzchni","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-12-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132601266","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}

Despite the fact that, in accordance with the global trend, the production of hydrocarbon carriers should be reduced, and in some countries, coal production has already been stopped (Germany), the energy sector of many countries is still to a great extent based on the use of coal. In this regard, improving the reliability of mining equipment is of great practical interest. To assess the reliability, predict the time to replace parts and plan the volume of production of spare parts, it is important for engineers to have the method for wear rate estimation. The method for this estimation, known since 1986, [1] was modified by the authors to clarify the defining constant in the equation. The clarification was made on the basis of experimental data, with the use of information from the literature and on the basis of experts’ recommendations.
