INCREASING OF WEAR RESISTANCE OF CUTTING EDGES BY COMBINED TREATMENT METHOD
Journal Title: Проблеми тертя та зношування - Year 2017, Vol 75, Issue
Abstract
The wear resistance of the operating surfaces of the cutting parts that been restored by com-bined treatment method which includes preliminary chemical-thermal saturation in powder mixtures and electric contact deposition of the achieved material under rational regimes is investigated. The effect of the powder mixture composition for the saturation of the surfacing tape on the distribution of the structural components and on it’s penetration depth in deposit-ed layer is explored. The influence of the structural components distribution in the deposited layer on the magnitude and the duration of the deterioration of the restored surface by the combined treatment method is investigated. It is determined that significant rise of the wear resistance of restored by combined treatment method surfaces is due to presence of the solid solution in the structure of deposited layer and to it’s subsequent hardening while the electric contact surfacing.
