Description
Technical Field
The invention belongs to the technical field of powder metallurgy, and particularly relates to YT15 hard alloy and a preparation method thereof.
Background
YT15 is a tungsten-cobalt-titanium hard alloy, is popular because of its high wear resistance and high hardness, is often used as a cutter material, and is particularly suitable for semi-finish turning and finish turning. The preparation of YT15 cemented carbide typically involves a powder metallurgy process. The process comprises the steps of uniformly mixing raw material powders of tungsten, cobalt, titanium and the like, and then forming the hard alloy through the steps of pressing, sintering and the like. The specific preparation process varies depending on the manufacturer's technology and equipment, but in general, the powder metallurgy process is the main method for preparing YT15 cemented carbide. The existing YT15 hard alloy still has certain defects: firstly, the toughness is insufficient, and although the YT15 hard alloy has high hardness and wear resistance, the toughness is relatively low. This means that it may be easily broken or damaged when subjected to an impact or a heavy load. Secondly, the processing difficulty is high, and the YT15 hard alloy can be relatively difficult to process and cut due to the high hardness of the hard alloy. Special cutting tools and machining techniques are required, which increases manufacturing costs and time. Thirdly, the thermal shock resistance is limited, and the YT15 hard alloy can be limited under the environment of high temperature or abrupt temperature change. This may lead to cracking or failure during use. Fourth, the price is higher, because the preparation process of YT15 hard alloy is complex and the cost of raw materials is higher, the price is relatively higher. This limits its use in some cost-sensitive application areas.
