The aim of the article is a hardening of the surface steel layers due to the combination treatment. Samples of steel 38Cr2MoAl were hardened by complex chemical and thermal treatment such as carburizing and subsequent boriding. It was established that sur... see more

Laser surface hardening of cast iron is not trivial due to the material’s heterogeneity and coarse-grained microstructure, particularly in massive castings. Despite that, hardening of heavy moulds for automotive industry is in high demand. The present pap... see more

Shot-peening is a surface mechanical treatment, widely used to treat metallic parts in the aerospace and automotive industries. This mechanical surface treatment should not be confused with other common applications of other peening treatments, oriented t... see more

The object of research are models that describe the effect of liquid glass and propylene carbonate as a hardener of the molding mixture on its properties. One of the most problematic places is determination of the behavior of the properties of the mixture... see more

The usage of the high-energy electron beam source enables repeated surface quenching of chosen locations of an engineering part surface. Different techniques of electron beam deflection allow creating hardened layers of different shapes, hardness levels a... see more

This paper introduces a novel multi-combined surface treatment consisting of the individual treatments of plasma nitriding (PN), physical vapour deposition (PVD) and electron beam hardening (EBH). Using graded surface layers produced by such a combined su... see more

Surface hardening, a process involving a wide variety of techniques, is used to improve the wear resistance of parts without affecting the softer, harder interior of the part. This combination of hard surface and resistance to breakage on impact is benefi... see more
