Abstract

The invention discloses a preparation method of a high temperature-resistant high-strength WC-Co-Ti3SiC2 hard alloy material. The method comprises the following steps: mixing titanium powder, silica powder, graphite powder and aluminum powder according to a molar mass ratio, and performing ball milling; sintering the ball milling powder in a protective atmosphere to obtain Ti3SiC2-TiC composite powder; mixing tungsten carbide powder, cobalt powder, Ti3SiC2-TiC composite powder, niobium carbide powder and vanadium carbide powder according to a mass ratio, and performing ball milling to obtain mixed powder; putting the mixed powder into a mould, and pressing with a single-shaft moulding press to obtain a billet; and sintering the billet material in a protective atmosphere, and forming to finally obtain a WC-Co-Ti3SiC2 hard alloy material. In the method disclosed by the invention, the Ti3SiC2-TiC composite powder replaces Co powder and serves as a binder, and the prepared WC-Co-Ti3SiC2 hard alloy has the characteristics of good mechanical properties at room temperature and high temperature, long life and the like.

Description

technical field

[0001] The invention relates to the technical field of new cemented carbide materials, in particular to a high-temperature-resistant and high-strength WC-Co-Ti 3 SiC 2 The preparation method of cemented carbide material. Background technique

[0002] Cemented carbide, also known as cermet material, is based on refractory metal hard compound (WC, TiC, TiN or Ti(C,N)) and uses metal as binder. Or high-strength wear-resistant materials prepared by powder metallurgy technology without chips and near net shape. The green manufacturing technology, excellent comprehensive performance and high cutting efficiency of cemented carbide make it the most widely used. Compared with TiC, TiN or Ti(C,N)-based cemented carbide, due to the better wettability of WC and metal binder, it is easy to form a uniform and dense transition phase, and form a high-performance interface to ensure that WC-based Excellent comprehensive performance of cemented carbide, especially high tem...
