Laser surface alloying of steel with TiC

Lasers Based Manufacturing

“…Therefore, TiC can be used as a suitable coating material for improving surface property of any metallic substrate. Laser alloying of AISI 1045 steel were performed by TiC powder and TiC + Ni-alloy (Ariely et al 1991;Ouyang et al 1995). Considerable numbers of works have been conducted by various research groups to improve the hardness, wear resistance and corrosion resistances of different structural materials with TiC or TiC reinforced metal matrix composite coating by laser surface engineering.…”

Laser deposited TiC/H13 tool steel composite coatings and their erosion resistance

“…Due to a relatively low cost, iron and steel as a coating matrix have potential application prospects. Utilizing laser surface alloying, Ariely et al [4] produced TiC reinforced steel coating on the surface of AlSl 1045 steel, which exhibits a higher hardness. Tassin et al [5] incorporated TiC into the surface of AlSl 316 L stainless steel by laser processing, which substantially improved sliding wear resistance.…”

“…Due to its high hardness, melting point, and thermodynamic stability as well as availability, TiC is extensively used as a reinforcing phase in MMCs' coatings, such as Ni-based [1][2][3] and steel-based composites [4][5][6]. Due to a relatively low cost, iron and steel as a coating matrix have potential application prospects.…”

Correlation of microstructure with hardness and wear resistance in (TiC,SiC)/stainless steel surface composites fabricated by high-energy electron-beam irradiation

“…In response to these problems, studies have been made to obtain the desired surface compositions and microstructures by using a laser beam on ceramics such as TiN, TiC, and SiC. [5,6,7] Recently, new attempts have been made by direct irradiation using a high-energy electron beam to achieve surface hardening or surface compositing. [8][9][10][11] When a high-energy electron beam irradiates on the material surface, the kinetic energy of electrons is converted to heat.…”
