Effect of N2 flow rate on the microstructure, mechanical properties, and dry-sliding behavior of Cr/CrN/LaB6-N multilayer coatings on AISI 4130 steel
Lanthanum hexaboride (LaB6) is a refractory ceramic widely used in electron-emission applications, whereas its potential as a nitrogen-modified protective coating for engineering steels remains insufficiently explored. This study presents, for the first time, a systematic nitrogen flow rate series of Cr/CrN/LaB6-N coat...
