Ploughshares during ploughing are worn as a result of friction with the soil. This process is accompanied by their heating. It was hypothesized that the amount of heat emitted in a given area of a ploughshare's surface is associated with the intensity of tribological processes. Using thermovision measurements, the temperature distribution on the rake face of ploughshares during use in soil was determined. It was found that the interaction of soil and ploughshares led to an increase in the temperature of their material. The landslide parts of the ploughshares were subjected to greater heating than the trapezoidal parts. On the working surface of the landslide parts, it was found that the greater heating area corresponded to a larger loss of thickness.
