Research of the regularities of the processes of formation of the surface layer in electric spark alloying

Purpose. Determination of rational parameters the process electrospark alloying 40X steel parts with different types electrodes. Measurement applied layer thickness using Mora Primus 564 coordinate measuring machine at customer's plant. To give recommendations on use processing modes in production when restoring parts. Research methods are based effective treatment metal surfaces and technology obtaining modified layers by treatment. Measurements were theoretical metrology modeling instrumental errors instruments, principles instrumentation mechanical engineering technology. The was used during measurements. results. Electrospark is one most common technologies for working metal, which characterized high accuracy productivity. In addition, adhesion strength base material provided, itself easy to perform technological operations has low energy consumption. analysis main factors influencing quality surface carried out. a sample investigated experimentally. During experiments, modern control equipment measurement used. Scientific novelty. For first time, vanadium, titanium tungsten have been determined. dependence electrode established. Recommendations given. Practical meaning. experimental researches out conditions allowed reveal basic regularities formation formulate coating certain thickness. This will restore worn part or strengthen new one.
