Oxidation of ultrafine-cemented carbide prepared from nanocrystalline WC–10Co composite powder
Source abstract
Abstract
Abstract The oxidation behavior and associated properties, phases and microstructure of ultrafine WC–10Co-cemented carbide using WC–10Co nanocomposite powder prepared by spray pyrolysis-continuous reduction and carbonization technology, were investigated in the 450–700 °C temperature range at 50 °C intervals. The results showed that the working temperature of the cutting edge should be lower than 550 °C in air without coolant in order to assure the lifespan and working efficiency of ultrafine WC–10Co-cemented carbide materials as cutting tools.
