The disc materials must possess specific requirements that allow the brake discs to function safely and effectively under the harsh conditions in which they operate. Based on their functions, brake disc materials should have high strength even at elevated temperatures, high thermal conductivity, excellent abrasion resistance, good creep resistance, high stiffness and superior corrosion resistance [2]. the current and future trends in the automotive industry are tending towards lightweight solutions [3], particulate matter (PM) and CO 2 emission reductions [4,5], improved corrosion resistant, cost reduction, and better performance and enjoyable driving experience. As a result of vehicles’ electrification, stringent government regulations regarding vehicle emissions and increasing demand for an enjoyable driving experience, several functional Abstract As electric vehicles are becoming more popular in society and several regulations concerning vehicle safety and performance as well as particulate matter emissions reduction are progressively becoming stringent, the author opines that these determinants would shape future automotive brake discs development.

Abstract Aluminum (Al) and its alloys are widely used in many industries, and anodic oxidation (AO) and plasma electrolytic oxidation (PEO) are two of the most important technical routes to improve their corrosion resistance and mechanical properties. This review paper covers both AO and PEO of Al alloys, in order to facilitate a comparison between the two technologies. A general overview of AO and PEO is provided. Then the focus is on PEO coatings, including the microstructure of PEO coatings, the effect of various PEO process parameters on the microstructure and properties of the coating. An attention is paid to the corrosion resistance and mechanical properties of PEO coatings on aluminum and its alloys. Finally, the applications of PEO coatings on Al alloys are summarized. The review intends to give a balanced coverage on recent development on PEO process and coatings, and to stimulate more research and industry interests in PEO coatings.","PeriodicalId":297187,"journal":{"name":"Modern Concepts in Material Science","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-11-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114543192","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}

At the same time, the thermal load on the fire walls of the combustion chambers (CS) of liquid rocket engines increases, which requires their protection from multiple thermal effects and the development of special coatings. One of the effective ways to increase the life of the most heat-loaded elements of the CS is the application of multilayer heat-resistant coatings [1,2], which have good erosion resistance and high thermal resistance in conditions of intensive exposure to high-temperature combustion products. The defining characteristic of such coatings is the adhesive strength of adhesion to the substrate, the quality of which depends on the preparation of the surface of the part under the coating Justification of methods of applying heat-resistant coatings Combustion chamber and jet nozzle (Figure 1) have a complex geometric profile and works with a large range of temperatures generated during combustion of the fuel. The technological process of plasma coating containing powders includes several operations [3,4], surface preparation, application of a sublayer (if necessary) and a layer of heat-resistant coating, and in some cases -subsequent mechanical and thermal treatment.","PeriodicalId":297187,"journal":{"name":"Modern Concepts in Material Science","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-08-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129594307","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}
