Specified coating materials are metal oxides, e.g. alumina, as well as metals and metal borides, carbides and silicides. The gas may be inert, oxidising, reducing, carburizing or nitriding.
Significant residual stresses are generated by non-uniform plastic deformation during operations like casting, forging, rolling, heat treatment, quenching, welding, shot peening, carburizing, and various other production techniques [36,37,38]. Additionally, preceding manufacturing processes, including ...
Ways to mitigate wear and erosion in gun barrels include liners, chromium plating, ablators, and wear-reducing additives to the propellant and low flame temperature propellants. 2. Theory of Gun Wear When a gun if fired the maximum bore temperature rises to about 1000oC in about the same ...

(Ref86,87). Besides these, traditional diffusion-based surface treatments such as carburizing/nitriding/aluminizing can also be applied to TS-HEA coatings to engineer their properties for targeted applications. The post-processing parameters must also be optimized with regard to the coating and ...
In an effort to reduce the influx of contaminating cold air and gases through the discharge door opening of prior art carburizing furnaces, a protective flame screen or curtain was directed across the face of door opening by means of an elongated burner disposed along the top of the door or ...
A brake disk is thus proposed in DE 10 2009 008 114 A1 with a tungsten carbide based coating, with the tungsten carbide coating applied by means of a thermal spray process having to be posttreated by means of carburizing, oxidizing, gas nitrocarburizing or another gas-based or plasma-based ...
