Title:
SELF-LUBRICATING CERAMIC CUTTING TOOL MATERIAL ADDED WITH NICKEL-PHOSPHORUS-ALLOY-COATED CALCIUM FLUORIDE COMPOSITE POWDER AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2018/120980
Kind Code:
A1
Abstract:
A self-lubricating ceramic cutting tool material added with nickel-phosphorus-alloy-coated calcium fluoride composite powder and a preparation method therefor. The self-lubricating ceramic cutting tool material consists of: 30‑48% of α‑Al2O3, 42‑66.5% of (W,Ti)C, 3‑12% of CaF2@Ni‑P by mass of CaF2, and 0.4‑1.5% of MgO. The preparation method of CaF2@Ni‑P comprises: coarsening CaF2 powders after being cleaned, adding the coarsened CaF2 powders with a sensitizing-activating liquid and performing ultrasonic vibration, and then performing chemical plating under conditions of a pH value of 8.5‑9.5, a temperature of 35‑45 °C and ultrasonic vibration.
