The paper investigates the effect of number passes (1 or 2) an indenter made fine cubic boron nitride during friction treatment PG-SR2 and PG-10N-01 NiCrBSi-coatings on micromechanical properties their surface layers. coating under all process conditions studied, in comparison with initial polished state, increases strength characteristics layer parameters indicating resistance material to elas...

In order to extend the service life of 45# steel and reduce production costs, coating NiCrBSi alloy powder on surface can meet requirements, avoid resource waste achieve green manufacturing. Based response method (RSM), dilution rate, aspect ratio contact angle were taken as optimization goals, process parameters (laser power, scanning speed feeding rate) optimized optimal determined. On this b...

Nickel-based alloys are commonly used as protective coating materials for surface protection applications owing to their superior resistance corrosion, wear and high-temperature oxidation. It is urgent study the fundamental mechanism between structure corrosion properties of Nickel-base composite coatings. This paper, therefore, focuses on clarifying mechanisms microstructure influencing acid m...
