Influence of ploughshare surface layers on ploughing efficiency

The paper presents comparison between standard ploughshares made of manganese steel 50Mn7 and the authors' ploughshares hardfaced with a layer of C-Co-Cr-Ni-Si on the same steel. The research was carried out by using two tractors with two four-furrow plough of the same power in a total of 360 working hours, and a total of 180 hours of ploughing with each ploughshare. Ploughshares were used to measure hardness, to analyse the structure and wear.
