Metallographic examination of carburized blasting wheel

Popis výsledku v původním jazyce

The present article is based on multiple examinations of a blasting wheel. According to specifications, the wheel is to be carburized to obtain a case depth of 4 mm. This requirement was set out by the designer in order to improve the wheel's life. On the other hand, there is an effort to keep the cost of the untreated part and the price of carburizing and quenching operations as low as possible, which in turn affects the selection of material suppliers and heat treating contractors. As a result of thiscost policy, the products are carburized in one heat treating shop and then heat treated in another. If the resulting part fails to meet specifications, it is difficult to identify the culprit. Omitting the tempering operation after quenching, as expressly specified by the designers on the drowing, proved another deficiency. The quality of this product has been monitored on a long term basis. Emphasis was laid on metallographic observation and on measurinf hardness profiles. Results of
