Creation of shock-abrasion resistance build-up metal using a physicochemical model of high-temperature processes

Build-up metal for shock-abrasion resistance was the focus of this work, where the mathematical model of physicochemical high-temperature processes developed by the authors in their previous works was used. A computer program based on the model permitted forecasting of the required chemical composition and structure of the build-up metal. Flux-cored wires were fabricated from a cold-rolled ribbon (1008 steel) and filled with a powder mixture. Low carbon steel (A 516) was used as the base metal. The specimens were prepared by 3-layered build-up. The prepared specimens were tested using light microscopy, scanning electron microscopy (SEM), energy dispersive X-ray analysis (EDS), hardness measurements, and shock-abrasion resistance measurements. The results of the above-mentioned tests confirmed the correct calculation of the model and the good shock-abrasion resistance of the suggested build-up metal.
