“…Therefore, special carbides in the matrix are produced, which cause undesirable embrittlement. 7 In the case of carbide, the carbides of Cr and W tend to precipitate along grain boundaries, which results in deterioration in toughness of the matrix metal. The consequence is a fissured coating with a strong tendency to spalling.…”

“…It is reported that wear resistance can be improved when hard particles are embedded in a tough, metallic matrix where the particles act as bearings for the sliding surfaces, reducing friction coefficients or preventing adhesive metal transfer. 7,8 In the recent developments, it has been shown that the toughness of the weld could be increased markedly when the carbides are granular in form and distributed evenly in the matrix metal. [9][10][11] Some strong carbide forming elements, such as niobium (Nb), titanium (Ti), vanadium (V) and zirconium (Zr) could combine with carbon to form granular carbides and decrease the carbon content in the matrix, which is favourable for improving the toughness of the coating.…”

“…len und damit hohe Kosten an teuren SchweiBzusatzen einzusparen, stellt das Beschichten rnit dem Plasma-HeiBdraht-Auftrag-(PHA)-SchweiBverfahren dar. Durch Einsatz moderner Steuer-und Regeltechnik sowie eines rechnergefuhrten ProzeBablaufs sind bei relativ hohen Abschmelzleistungen Beschichtungen von hoher Reinheit rnit sehr guten Schichteigenschaften moglich, wodurch sich dieses Verfahren in vielen Untersuchungen bewahren konnte[12][13][18][19]. Es zeichnet sich durch die erzielbare geringe Lagendicke von 2 bis 3 nun verbunden rnit sehr geringen Aufmischungsgraden von < 5% aus.…”
