Livshits V.B., Bobkova E.S., Dryukova A.E., Popov E.I. An influence of irradiation conditions at chemicaland-thermal radiation treatment on the erosion resistance of press-molds
An influence of various parameters of strengthening of pressing tools by chemical-and-thermal radiation treatment (CTRT) on the erosion resistance of the shape-making parts of press molds (PM) used at casting with crystallization under pressure (CCUP) is studied. It is shown that the highest erosion resistance of the press molds is achieved at certain irradiation energies and by heating of the tooling. The obtained parameters were checked under industrial conditions. It has been stated that the maximum strengthening of the shape-making parts of press molds is achieved under the studied conditions of strengthening at the chemical-and-thermal radiation treatment, when the erosion resistance of press molds increases 3–3.5 times as compared to the strengthening provided by conventional technology, which consists of the chemical-andthermal treatment (CTT) only.
Key words:Strengthening, casting with crystallization under pressure, chemical-and-thermal radiation treatment, irradiation with electrons.
