TiN and Boride Layers Obtained by Dehydrated Paste-Pack Boriding and PVD Treatments Formed on AISI M2 Steel

Effect of thermochemical treatments on the surface hardening of a circular saw blade: A microstructure comparison of nitride layers, boride layers and TiN coating formed on ASTM A1011 steel

“…The compound layer is often composed of ε-Fe3N1+x and γ′-Fe4N nitrides [1]. Likewise, thermochemical boriding of iron alloys allows both single Fe2B and FeB-based polyphases coatings to be obtained and then used mainly to improve surface hardness (up to 2000 HV) and wear resistance of the components for tribological applications [2][3][4][5][6]. Finally, PVD (physical vapour deposition) is the one of the ways of their deposition onto tool steels substrate.…”

Microstructure and mechanical properties of borided AISI T1 high-speed steel by dehydrated paste-pack boriding

“…The estimated market volume worldwide for hard coatings in 2015 was about US$2.6 billion. Surface hardening treatments used in the metal-mechanic industry generally fall into two categories, diffusion (carburizing, nitriding, boriding, and carbo-boro-nitriding) and overlay coating (PVD) [1][2][3][4][5][6][7][8][9][10]. The objective of this study was to analyze the microstructure of the Fe2B layers formed on an AISI T1 high-speed steel and to study the wear properties of Fe2B layers.…”

Wear Properties of TiN Coating on AISI M2

“…Application of hard coatings to improve the resistance of tooling to withstand adhesive and abrasive wear underwent a significant development program within the past decades. Surface hardening treatments used in the metal-mechanic industry generally fall into two categories, diffusion (carburizing, nitriding, boriding, and carbo-boro-nitriding) and overlay coating (TiN) [1][2][3][4][5][6]. A hard layer on a soft surface can reduce friction and wear by preventing fissuring at both the macro and the micro-level.…”
