Sažetak


Prah Mo&O2 ima značajnu ulogu u proizvodnji prevlaka sa povišenom otpornošću na klizanje u uslovima bez primene maziva. Prevlake Mo&O2 imaju mali koeficijent frikcije i dobre karakteristike na habanje pri mehaničkim naprezanjima. Radi proizvodnje prevlaka visoke tvrdoće, prah Mo&O2 je deponovan plazmom sa optimalnim parametrima. Karakterizacija oblika površine čestica oksidnog praha i površine preloma prevlake izvedena je metodom SEM, a mikrostruktura slojeva primenom svetlosne mikroskopije. Mikrostruktura prevlake sastoji se od lamela Mo i tankih filmova primarnih oksida MoO2 i MoO3 koje okružuju lamele Mo. Analiza dobijenih rezultata pokazala je da slojevi prevlake Mo&O2 sa difuziono oksidiranim česticama Mo imaju strukturu i mehaničke karakteristike koje omogućuju njenu primenu na površinama radnih delova u uslovima habanja i klizanja trenjem bez maziva.
