Comparative tests of plasma-surfaced nickel layers with chromium and titanium carbides

Application of design of experiment to a FCAW process

“…The important issue in welding protect surface technologies is the correct determination of parameters affecting the quality and properties of the cladding surface. Changes of settings of the parameters give us the chance to gain deposit layers of a different microstructure, hardness and surface without defect [7,[12][13][14][15].…”

“…Adding hard particles carbides to the core is especially possible in the core. Determining material durability on wear is determined by two factors: hardness and structure [1,10,[12][13][14][15][16][17][18][19][20].…”

Using experimental design to determine the wear resistance of the padded layers by FCAW

“…Chotěborský et al (2011) tested cladding technology without preheating before cladding and with air cooling after process. Pernis et al (2013) checked a pulsed power source, and the application of the plasma method was described by Bober et al (2016).…”

“…Both cladding and thermal spraying technologies are widely applied to fabricate wear resistance surface layers. The layers fabricated on substrate materials may contain in near surface areas primary complex carbides or other phases having hardness up to 3000 HV (Bober et al, 2016).…”

“…The hardness of wear-resistant layers depends on the used materials and welding techniques. Particularly in core materials there is the possibility of put in hard carbides to the core of the wire (Gucwa et al, 2015, andBober et al, 2016).…”
