title = "The use of reactive gas shielding for production of hard coatings by laser surface alloying",
abstract = "A computational thermodynamic model was used to guide the generation of composite hard coatings made of hard particles distributed uniformly in a steel matrix. The calculations suggested that precipitation of titanium carbonitrides in liquid steel could be achieved by increasing the supersaturation of carbon, nitrogen and titanium in liquid steel. This condition was achieved by nitrogen addition to shielding gas during laser surface alloying while laser melting and solidifying a mixture of 431-type stainless steel and titanium carbide powders. With 100\% nitrogen shielding deposits exhibited increased hardness compared to that of 100\% argon shielding.",
