Formation and Bonding of Hot Melt Coatings - Bonding Forms of Thermal Spray Coatings and Substrates

       Combination form of thermal spray coating and substrate

 

     There are many types of thermal spray coatings. In terms of composition, there are pure metals, alloys, ceramics, composite materials and polymer materials. From the perspective of the supply form of materials, it can be divided into wire, powder and so on. Due to the great compositional coverage of these materials, their combined form with the substrate is also great. From the perspective of the source of bonding force, it can be summarized as metallurgical bonding, physical-chemical bonding and mechanical fitting. The matching of thermal spray materials and substrates is different, and the proportions of these combination forms in the combination are also different.
