Description
| - Porosity is one of the factors that influence mechanical and thermal properties of the thermally sprayed deposits. From all of the characteristics of the pore network, the intersplat interface, characterized by the thickness of oxide layer and width of intersplat cavity appears to play the crucial role. Tungsten has second highest melting point of all metals, and the coatings of W are of high industrial importance. The optimization of W deposit properties is impossible without knowing the effect of porosity on the properties of the final deposit. Thus the intersplat porosity of W deposits prepared by RF-ICP and DC-WSP plasma at different substrate temperatures was characterized. Metalographically prepared cross-sections were observed in SEM and evaluated by a newly developed image analysis method. The method is based on combination of fiber detection and distance mapping. Correlation was found among pore width distribution, Elastic modulus and Hardness of the deposits. The effect of process parameters and particle in-flight properties on the intersplat interface was also discussed.
