Preparation of Carbidostals

Abstract

The article discusses a powdered material - carbidostal. Comparative characteristics of carbidostals, tool steels are given and hard alloys. Methods of producing and producing carbidostals are considered. Conditions for free separation of residues of impregnating material from the surface of the article are established. The reasons of volumetric change of amount of carbides and binding by height of impregnated press are studied.

Quantitative Evaluation of the Effectiveness of Laser Surface Modification Technologies

“…For intermediate values the relationship is stronger if the correlation coefficient is closer to one. The calculating method of correlation coefficients offered in [10] was used for processing the experimental results in paper [8]. As a result of calculations, the pair correlation coefficient for the reduced wear and the reduced integral microhardness Y ′ of the modified surface layer is equal to 0,73.…”
