[ 1 ] - Structural characteristics and tribological properties of TiAlCr(Si)CN nanocomposite films coated on the SPK 1.2080 tool steel using PVD technique
In the present work, structural characteristics and tribological properties of the Ti-Al-Cr-(Si)-C-N nanocomposite films coated on the SPK 1.2080 tool steel byPVD technique have been investigated. The PVD coating process was carried out using Ti (Si) Al and CrAl cathodes at 150 A current, 40 V bias and (Ar)0.1(CH4)0.45(N2)0.45 gas mixture for 50 min. Evaluations were conducted by OM, FESEM, AFM...
[ 2 ] - INFLUENCE OF SURFACE NANO/ULTRAFINE STRUCTURE ACHIEVED BY DEEP ROLLING PROCESS ON PLASMA NITRIDING AND TRIBOLOGICAL PROPERTIES OF THE AISI 316L STAINLESS STEEL
Influence of formation of surface nano/ultrafine structure using deep rolling on plasma nitriding and tribological properties of the AISI 316L stainless steel was investigated. Initially, the deep rolling process was carried out on the bar-shaped specimens at 15 cycles with 0.2 mm/s longitudinal rate and 22.4 rpm bar rotation. Then, plasma nitriding treatment was applied on the as-received...
