Characterization of Coatings Obtained by Dehydrated Paste-Pack Boriding Process Formed on AISI A36 Carbon and 304 Alloy Steels

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

“…Cost of tool is also not negligible. A proposed solution consist of developing a hard, dense, wear-and corrosion-resistant coating formed on a surface with certain affinity in fracture toughness, as well as the creation of a dislocation interface that prevents the propagation of the corrosive medium to the substrate and the propagation of micro-cracks [1][2][3][4][5][6][7][8][9][10][11][12]. In particular, nitriding of tool surfaces is one of the most commonly used types of heat treatment of tool steels.…”

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.…”

Recycling of the Powder-pack Boriding Mixture: Microstructural Characterization of Fe2B Layers on ASTM A36 Steel

“…These phases consist of orthorhombic and tetragonal lattices (body-centered) respectively. One basic advantage of boride layers is that they can reach high hardness values (between 1800-2000 HV), kept at high temperatures [1][2][3][4][5][6][7][8]. In the present study, the microstructure of the single phase layer (Fe2B) and the recycling of the powder-pack boriding mixture until it is no longer possible to form any layers on the surface of the ASTM A36 borided steel have been investigated at 1173 K with exposure time of 2 h by dehydrated paste-pack method.…”
