Abstract
The properties of carbide coatings on carbon steel were studied in this paper. Process was made
in saturating mixtures with the use of iron-alloy powders. There were various ratios of these
powders. It is found that the two-component coating have higher wear resistance under dry sliding
friction than one component coatings. The mathematical modeling was carried out with simplex
planning method. The composition of the mixture which provides the maximum durability was
determined
