Abstract
The invention discloses a high temperature-resistant and wear-resistant valve seat ring. The valve seat ring is prepared from powder metallurgical material, wherein the powder metallurgical material comprises the following components in percentage by weight: 0.3-1.2% of C, 4-7% of Mo, 4-9% of Co, 0.5-1.4% of Mn, 3-7% of Cr, 1.5-1.6% of Cu, 0.02-0.08% of P, 0.2-0.5% of V, 5-7% of W, 0.2-3.5% of Ni and the balance of Fe. The formula of the high temperature-resistant and wear-resistant valve seat ring disclosed by the invention is reasonable; by adding a variety of wear-resistant and high temperature-resistant metal elements, the wear resistance and the high temperature resistance are effectively improved. The high temperature-resistant and wear-resistant valve seat ring disclosed by the invention has the characteristics of high density, high hardness, heat resistance, excellent resistance to thermal shock, good machining performance and the like, and can effectively improve the quality of a product.
Description
?
Technical field
The present invention relates to a kind of internal combustion engine part, be specifically related to a kind of heat resistant and wear resistant valve retainer.
Background technology
Valve retainer for automobile engine is parts important on engine, enters air and combustion while being automotive fuel burning
The door of combustion gas after burning, its main purpose is the sealing that ensures combustion chamber.At present, commercially available powder metallurgy valve seat circle is mainly iron-base steam valve base made by powder metallurgy circle, and it is mainly to add chrome molybdenum powder and graphite, Zinic stearas with iron powder, mixes by proportioning, forms through die forming, the follow-up machining of sintering infiltration.In this production method, because composition complexity, the starting material density difference of material are large, therefore there is lack of homogeneity, shortcoming that production cost is high in finished product, and do not reach the performance requriements of component market product, serious restriction enterprise development is because working conditions is severe, impact, the wearing and tearing that need under hot environment, bear valve, and the effect such as erosion, oxidation of inlet and outlet stream, therefore, the characteristic such as high temperature resistant, wear-resistant, anti-oxidant of valve retainer is had to high requirement.Along with scientific and technical development, people are more and more tighter to the requirement of engine valve retainer, wish that valve retainer has higher thermotolerance, wear resistance and erosion resistance.
Summary of the invention
The object of the invention is to provide a kind of high temperature resistant, anti abrasive valve retainer.
The solution of the present invention is as follows: a kind of heat resistant and wear resistant valve retainer, described valve retainer is made up of mmaterial, wherein, the weight percentage of mmaterial consists of: C0.3～1.2%, Mo4～7%, Co4～9%, Mn0.5～1.4%, Cr3～7%, Cu1.5～1.6%, P 0.02～0.08%, V 0.2～0.5%, W5～7%, Ni 0.2～3.5%, surplus are Fe.
Described valve retainer is made up of mmaterial, wherein, the weight percentage of mmaterial consists of: C0.8%, Mo6%, Co7%, Mn1.2%, Cr4.5%, Cu1.45%, P 0.05%, V 0.35%, W6.4%, Ni 0.25%, surplus are Fe.
Formula of the present invention is reasonable, add multiple wear-resistant and resistant to elevated temperatures metallic element, effectively improved wear resistance, high thermal resistance, the present invention has the features such as density is high, hardness is high, heat-resisting, thermal shock resistance is good, machinability is good, effectively improves the quality of product.
