In order to reduce the cost,two types of superfine iron powder from two domes-tic companies were used.The article tested the particle size,morphology,and oxygen content of two types of powders,compared the powder's compaction formability and sin-tering performance,and conducted comparative experiments on the amount of powder used in the formula of sintered diamond saw blades.The hardness,bending strength,and cutting performance of the product were tested,and the results showed that the applica-tion of superfine iron powder in the diamond saw blade matrix had good effects on product sharpness and service life,by combining different superfine iron powders and leveraging their respective advantages,the application effect is better.
