Abstract

Inventia se refera la un procedeu pentru durificarea suprafetelor active ale cutitelor de retezat la cald bare din otel pentru rulmenti, utilizat în scopul cresterii durabilitatii în exploatare. Procedeul conform inventiei consta în depunerea unui strat pe suprafetele active, prin sudare electrica cu electrozi înveliti, urmata de un tratament termic de precipitare si de tensionare.
