Dialing in the perfect hard coating

Got something to say to this podcast? Send a voicemail, and you might hear yourself on the next episode! In this episode, Elena and Marcus unpack "Varying Ti concentration effects on TiBx coatings deposited via dual HiPIMS of TiB2 and Ti targets", published as a Surfaces and Interfaces 2026 paper. Dual HiPIMS with separate Ti and TiB2 targets (TiB2 fixed at 500 W, Ti varied 50–250 W) tunes the B:Ti atomic ratio from 2.4 down to 0.68, giving precise stoichiometry control that conventional sputtering struggles with. Part of a series covering all 575 of Prof. Volinsky's publications, one episode at a time. Paper DOI: 10.1016/j.surfin.2026.109301. Note: voices in this episode are AI-generated: Elena and Marcus.
