Formation and Bonding of Hot Melt Coatings-Characteristics of Fusion Bonding

       Characteristics of fusion bonding

 

     The meaning of sintering is wider, and there are many methods used. The methods commonly used in production are oxyacetylene flame powder spray melting (spray welding), plasma spray melting (spray welding) and vacuum fusion. The coating materials they use are mostly self-fluxing alloy powders.

 

     Sintering generally includes two processes, spraying (or coating) and remelting (or sintering). The former is to spray (smear) the coating material on the surface of the workpiece, and the latter is to use a heat source to heat the coating material to a molten state, wet the workpiece, and perform reactions such as deoxidation and slag formation of self-fluxing alloys in order to obtain a firm bond. cladding layer.
