Abstract

The invention provides a high strength powder metallurgy material comprising, by mass, 80-100 parts of iron, 5-6 parts of titanium, 2-3 parts of stibium, 2-3 parts of calcium, 1-2 parts of aluminum, 3-5 parts of carbon, 0.5-1 parts of graphite, 1-2 parts of molybdenum disulfide, 0.5-1 parts of strengthened nickel, and 2-3 parts of a lubricant. According to the high strength powder metallurgy material, multiple metal raw materials and additives such as the carbon, the molybdenum disulfide, and the lubricant are utilized to produce according to a specific mixing ratio, and the fusion performanceis good. A workblank obtained by using the powder metallurgy material is easy to demold, the surface quality is good, and the quality is uniform and fine.

Description

technical field [0001] The invention belongs to the technical field of metallurgical materials, in particular to a high-strength powder metallurgy material. Background technique [0002] Powder metallurgy is a processing method that uses metal powder as raw material to make various products by pressing and sintering. The essential advantage of the powder metallurgy parts production process is the rapid prototyping capability of complex parts and high material utilization. [0003] The raw material of powder metallurgy is metal powder, which is mainly composed of various metal raw materials decomposed into fine particles and mixed. Due to the difference between powder metallurgy materials and casting processes, metal powders are often difficult to fuse well, and it is even difficult to demould after compaction. Especially when producing some complex structural parts, the yield is low, and formula improvement is required. Contents of the invention [0004] The purpose of t...
