Abstract

The invention discloses a powder metallurgy material which is composed of, by weight, 73-82 parts of iron, 2-3 parts of nickel, 0.5-1 part of manganese, 1-2 parts of titanium, 0-1 part of molybdenum, 12-15 parts of chromium and 3-5 parts of additive. The additive comprises, by weight, 3-5 parts of graphite, 2-3 parts of anti-wear agent and 4-6 parts of lubricating agent. By means of the mode, the powder metallurgy material is prepared by adopting multiple raw materials and the additive according to a specific ratio, and a manufactured press blank is easy to demould, even and fine in texture, good in surface quality and high in product qualified rate.

Description

technical field [0001] The invention relates to the field of powder metallurgy material formula, in particular to a 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 different processes of powder metallurgy and casting, metal powder is often difficult to fuse well, and even it is 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 technical problem mainly solved by the inve...
