One of the key advantages of cold spray is the minimal heating of the substrate during the coating process. This is particularly beneficial for materials that are sensitive to heat, as it avoids potential issues such as thermal distortion, oxidation, or phase changes. Additionally, the lack of heat generation results in compressive residual stresses in the spray-deposited material, which enables the creation of very thick deposits, ranging up to many centimeters.
比較する場合コールドスプレー and thermal spray, it is clear that each method has its own unique advantages and disadvantages. Cold spray offers minimal substrate heating, high-density coatings, and the ability to produce very thick deposits. It is particularly suitable for applications that require high durability and resistance to corrosion, wear, and erosion.
