EXAMINATION OF OVERLAID WELD CLADDING WITH ADDITION OF NANOSIZED DIAMOND PARTICLES

Plamen Tashev, Rumyana Lazarova, Seryoja Valkanov,Rositsa Dimitrova, Vladimir Petkov

A method for deposition of chrome finish with nano-diamonds on specially prepared samples representing T-shaped weld joints with a separate cavity in the area of the root of the second seam is developed. One group of samples are prepared with chrome plating and the other group is prepared with chrome-nano diamonds (ND) plating with. The second seam is applied on the both types of samples with different plating. During the metallographic examination of the weld joints, difference was found in the microstructures of the root zone between the two types of samples. Increased micro hardness is registered in the root zone, which is supposed to contain the highest concentration of ND particles and hence to be the most strongly influenced by them.
