Abstract
The invention discloses a method for improving copper component segregation of a powder metallurgy structure part. The method is characterized by comprising the following steps of: arranging iron-based powder in a chemical solution containing copper ions, carrying out a replacement reaction on the iron-based powder and the copper ions, and uniformly coating a copper powder layer on the surface of the iron-based powder; and separating and processing the iron-based powder on the surface of which the copper powder is coated from the solution. Compared with the prior art, the method has the advantages of high mixing uniformity, excellent product batch performance and high consistency.
Description
Technical field
The present invention relates to a kind for the treatment of process of iron-based powder, be specially the method for utilizing substitutional alloy to improve the segregation of powder metallurgy structural parts copper component.
Background technology
In order to improve the mechanical performance of powder metallurgy structural parts, usually add copper, and when adding copper, generally be directly to add copper powder, but because the proportion of each component is different and powder particle size varies in size, very easily cause the component segregation of compound, because the mechanical performance of product relies on the composition of chemical composition, thereby have a strong impact on performance uniformity and the uniformity of bulk article.
Therefore, at Powder Metallurgy Industry, the segregation of ferrous based powder metallurgical constitutional detail copper component still is to have a strong impact on product chemical composition uniformity, thereby affects product mechanical performance uniformity and conforming principal element.
Summary of the invention
In order to address the above problem, the invention provides a kind of method of improving the segregation of powder metallurgy structural parts copper component, compared with prior art, this technique have mix, the equal even conforming advantage of product batches performance.
For achieving the above object, technical scheme of the present invention is:
A kind of method of improving the segregation of powder metallurgy structural parts copper component may further comprise the steps:
A, iron-based powder is placed the chemical solution that contains copper ion, iron-based powder and copper ion generation displacement reaction are covered with one deck copper powder at the surface uniform of iron-based powder;
B, the iron-based powder that above-mentioned surface is covered with copper powder break away from from solution;
C, the iron-based powder of step b is processed.
The above-mentioned method of improving the segregation of powder metallurgy structural parts copper component, the iron-based powder that will be covered with copper powder after the described step b, before the step c cleans, drying.
The above-mentioned method of improving the segregation of powder metallurgy structural parts copper component, the content of copper adds according to the technical recipe required amount in the chemical solution that contains copper ion of described step a.
Among the present invention:
The solution that contains copper ion refers to the solution that contains the water-soluble rear formation of cupreous compound that some are soluble in water.
Processing described in the step C refers to prior art, such as: compacting etc.
Principle of the present invention and beneficial effect show:
The present invention has abandoned and had directly added copper powder with its process of mixing with iron-based powder in the past, and employing displacement reaction principle, surface at iron-based powder all evenly has one deck copper powder, like this copper powder and iron-based powder no matter in which angle, no matter how blending all can guarantee very to mix, solved copper powder varying in size with powder particle size because proportion is different from iron powder in the blending process, the component segregation phenomenon of the compound that causes, in the blending process, mix, guaranteed all even uniformity of product batches performance.
Below in conjunction with the specific embodiment innovation and creation are described further.
The specific embodiment
A kind of method of improving the segregation of powder metallurgy structural parts copper component may further comprise the steps:
According to the quality of technical recipe and iron-based powder, calculate the quality of the copper powder that will add, then according to concrete type of adding copper compound, calculate the amount of adding compound, then the water-soluble formation of compound is contained the chemical solution of copper ion.
A, iron-based powder is placed the chemical solution that contains copper ion, iron-based powder and copper ion generation displacement reaction were reacted 3-10 minute, were covered with one deck copper powder at the surface uniform of iron-based powder;
B, the iron-based powder that above-mentioned surface is covered with copper powder break away from from solution, clean up, drying;
C, the iron-based powder of step b is processed.
Processing among the step C refer to existing routinely processing, such as the compacting etc.
Preferably, above-mentioned chemical solution satisfies: containing the solution that contains iron ion after the chemical solution of copper ion and the displacement should be soluble in water, be convenient to clean, and avoid unnecessary impurity to be blended in the iron-based powder, cause secondary to mix inhomogeneous and affect quality stability.
