Melt lubricants have excellent anti-friction, anti-wear and anti-oxidation properties and are used in the hot metal forming process for steels. TZM alloy is a promising forging die to replace H13 steel in the hot metal forming process. In this study, the high temperature wettability and high temperature tribological performance of borosilicate glass on H13 steel and TZM alloy were studied. The results suggest that the glass has good wettability on the hot H13 steel and promising lubricating with coefficient of friction of 0.06 at 900 ℃. However, the same glass shows poor wettability and lubricating for the TZM alloy. It indicates that high temperature wettability is also one of the key parameters that influence the tribological performance, rather than the well-known high temperature viscosity. Surface and interface characterization indicates that the Fe<sub>2</sub>O<sub>3</sub> induced enrichment of the network modifier Na<sup>+</sup> near the substrate surface, the dense and shearable low-oxygen permeable glass film led to the excellent oxidation resistance and lubrication properties in the friction system of H13 steel (pin). The erosion of the borosilicate melt by MoO<sub>3</sub> leads to poor adhesion, the phase separation behavior of the glass polymerization zone and the molybdate depolymerization zone. The melting state of the low melting point species make the TZM alloy (pin) friction system exhibit complex friction behavior. This work will provide some guideline for the structure and wettability control for promising high temperature lubricating.</div></div>","PeriodicalId":23238,"journal":{"name":"Tribology International","volume":"202 ","pages":"Article 110360"},"PeriodicalIF":6.1,"publicationDate":"2024-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142660420","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, limited efforts have been made to examine the influence of Erbium (Er) in Mg alloys. This study is designed to unravel the role of Er addition on wear and friction characteristics of Mg-Er alloys. As-cast Mg-Er (0.5–12 wt%) alloys were prepared and tested under dry sliding conditions with varying normal loads (5 N to 100 N) and sliding speeds (0.01 m/s to 0.1 m/s). The results indicated that the addition of Er to Mg significantly improved the overall wear properties of the alloys. At higher Er content, a substantial decrease in severe wear rate region (75 %), while a ⁓ 40 % reduction in friction coefficient were observed. The formation of a protective tribo-oxide layer at the contact zone due to the increase in temperature from friction, combined with the strengthening effect of the Er-rich precipitates, contributed to enhanced wear resistance with Er addition. The surface energy of the Mg-12Er alloy was less than that of other Mg-Er alloys (⁓ 50 % reduction), causing reduced adhesion and abrasion wear and thus reducing the overall wear rate. Furthermore, it was observed that higher applied normal loads led to increased wear rates and friction coefficients, whereas with increasing sliding speed, the wear rate was reduced. Major wear mechanisms observed were abrasive, adhesive, plastic deformation, oxidation, and fatigue wear along with delamination.</div></div>","PeriodicalId":23238,"journal":{"name":"Tribology International","volume":"202 ","pages":"Article 110337"},"PeriodicalIF":6.1,"publicationDate":"2024-10-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142539481","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
