By a News Reporter-Staff News Editor at Journal of Technology -- Current study results on Thin Solid Films have been published. According to news reporting from Hsinchu, Taiwan, by VerticalNews journalists, research stated, "In this study, five Cr-Ti-B-N thin films with different B/(Cr + Ti) ratios ranging from 0.1 to 0.69 were fabricated on silicon substrates and AISI420 stainless steel disks by pulsed DC magnetron sputtering using the Cr and TiB2 targets. It was found that the B content had strong influences on the structures and mechanical properties of Cr-Ti-B-N coatings."
The news correspondents obtained a quote from the research from National Tsing Hua University, "When the boron content reached 17 at.%, the microstructure changed from the nanocolumnar structure to a nanocomposite structure with nanograins around 4 nm in diameter embedded in the amorphous matrix. As compared with Cr-B-N coating, the solution hardening effect was found to result from the addition of Ti element. The average surface roughness, hardness and elastic modulus of Cr-Ti-B-N film decreased with increasing B content due to the amorphous BN phase. No chipping failures were found adjacent to the scratch track or indentation craters of each coating."
According to the news reporters, the research concluded: "In this study, the 37.3 Cr-2.3 Ti-4.0 B-56.0 N (in at.%) coating provided an optimal combination of hardness, wear resistance and adhesion."
