Among these coatings, Aluminum Titanium Nitride (AlTiN) is widely recognized for its excellent mechanical and thermal properties, making it a popular choice for industrial cutting applications. Despite its growing adoption by coating solution providers, there remains a limited understanding of the influence of key HPPMS process parameters on the development of high-performance AlTiN coatings. This study investigates the effects of two critical process parameters—substrate bias and target frequency—on the deposition of AlTiN coatings. The wear behavior of the coated tools was assessed through turning tests, evaluating their performance under industrially relevant conditions. Additionally, the challenges of depositing coatings on tools with complex geometries were addressed. The findings provide valuable insights into the optimization of HPPMS process parameters, contributing to the development of advanced coatings with enhanced wear resistance and improved performance in cutting applications.</div></div>","PeriodicalId":34140,"journal":{"name":"Open Ceramics","volume":"21 ","pages":"Article 100746"},"PeriodicalIF":2.9,"publicationDate":"2025-01-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143159393","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is shown that for a silica refractory with porosity 21 % the experimentally measured thermal conductivity (1.3–1.6 W/mK) is significantly lower than the analytical and numerical predictions for spherical, polyhedral and concave pores (3.1–4.7 W/mK), which indicates the influence of microcracks.
