This paper presents research of influence electrolyte plasma carbonitriding on tribological properties of R6M5 high-speed steel. Shows perspectiveness of carbonitriding high-speed steels in electrolyte plasma. The results of research demonstrated increasing wear-resistance of R6M5 steel after carbonitriding in electrolyte plasma. Under the same test conditions by the method of scratch-test have been determined that the depth of the scar of a modified layer has become less in comparison with the original sample, which indicates a significant increase of wear-resistance and hardness of the surface carbonitriding layer R6М5 steel. It was set that after electrolytic-plasma carbonitriding abrasive wear-resistance of the surface layers of R6M5 steel is increased by 25%. Introduction

Swelling Soil

Columns of aggregates of a soil, which slakes into microaggregates of about 30 � diameter as well as swelling on quick wetting, were examined by high speed photography during infiltration. Because of the collapse of the original structure of surface layers, the supply of water to deeper layers is restricted. Examination of motion pictures and magnified stills for the depth zone just below the collapsed surface layer provides a description of the phenomena occurring during the advance of the front. These phenomena are discussed in terms of limitations of the procedure used, the mechanism of wetting, the displacement of particles, infiltration behaviour, and the nature of swelling and slaking in these systems.

The research depicts structural picture of the steel surface layers after pulsed laser treatment with surface reflow. There are factors contributing to the dispersion of forming crystals to the nanoscale level. There is also found interdependence of nanostructure and laser-irradiated products strength characteristics.
