Abstract
The invention relates to an engineering material, particularly to a titanium carbonitride-base metal ceramic material for sealing pumps, valves and other machines. The titanium carbonitride-base metal ceramic material is prepared from Ti (C, N) powder, which has wide sources and low cost, as basic material, and binder, inhibitor and other additives as adjuvant materials. The preparation method comprises the steps of completely mixing the raw materials in ethanol or acetone solvent, drying, pressure moulding, placing the obtained blank into a reaction furnace, performing liquid sintering under vacuum or gaseous protection condition, and optimizing to obtain dense material with high hardness, and high bending strength and fracture toughness property. The inventive material has the advantages of resistance against high temperature, corrosion and abrasion, and low cost; and can be used for sealing pumps, valves and other machines. The preparation method has the advantages of simple process and applicability to industrial production; and has wide market application prospect.
Description
Technical field
The present invention relates to a kind of engineering materials, specifically be applicable to the base titanium carbonitride material that mechanical seals such as pump class, valve class are used.
Background technology
At present, the machinery sealing material as the pump housing, valve type mainly contains following several: (1) elastomeric material; (2) asbestos material; (3) metallic substance.Rubber system sealing material is aging easily, and tolerable temperature pressure is lower, and corrosion-resistant because the elasticity of rubber itself has increased the frictional force between sealing material and the matrix, had both been aggravated wearing and tearing between the two in addition, made opening-closing valve comparatively require great effort again; There is short, perishable shortcoming of life-span in the asbestos sealing material, causes damage thereby have to often change sealing material for this reason; Metallic seal material price costliness, stopping property are relatively poor.Though thereby existing multiple sealing material can not satisfy the pump housing, the application of valve type machinery sealing material in modern industry owing to lack practicality and the suitable ratio of performance to price.
Ti (C, N) based ceramic metal is a kind of new ceramic material that occurs the seventies in 20th century, it has high-melting-point, high rigidity, performance characteristics such as wear-resistant, corrosion-resistant, anti-oxidant.In addition, and Ti (C, N) the based ceramic metal source is abundant, and price is cheap than the common metal material.Therefore (C, N) based ceramic metal had both satisfied the pump housing to Ti, the valve type sealing material is high temperature resistant, corrosion-resistant, anti abrasive practical requirement, had satisfied the requirement of cost performance again, was the ideal candidates material of sealing material, had wide market application prospect.
Summary of the invention
The object of the present invention is to provide a kind of long service life, good airproof performance, the pump housing and valve type machinery sealing material that cost performance is high,, reduce the sealing cost, the normal operation of support equipment to improve airtight quality.
The objective of the invention is to be achieved through the following technical solutions:
Be utilize wide material sources, (C, N) powder is a basic material to cheap Ti, is aided with binding agent, grain inhibitor and other additive.With these raw materials thorough mixing in ethanol or medium-acetone; carry out technologies such as drying, compression moulding then; place Reaktionsofen under vacuum or gas shield condition, to carry out liquid phase sintering pressed compact; obtain the dense material of high rigidity, high-flexural strength and fracture toughness property by optimizing technology, thereby satisfy the performance requirement of the pump housing, valve type machinery sealing material.
Further be that described binding agent is a kind of of Fe, Co, Ni or their mixture.
Further be that described grain inhibitor is Mo, Mo
2C, VC, Cr
3C
2A kind of or their mixture.
Further be that described other additive is a kind of of WC, TaC, NbC, HfC, C, Y, Er, SiC whisker or their mixture.
Further be that described shielding gas is a kind of of high-purity argon gas, nitrogen or their mixed gas.
Further be that described Reaktionsofen is hot-pressed sintering furnace, tube furnace, induction furnace, microwave agglomerating furnace, discharge plasma sintering stove, rotary kiln, carbon tube furnace, shaft furnace, grate, pushed bat kiln or tunnel furnace.
Utilize the bending strength＞2000Mpa of the base titanium carbonitride material of technical scheme preparation of the present invention, hardness HRA＞92.0 have excellent mechanical property.
Compare with the existing machinery sealing material, the base titanium carbonitride material that the present invention uses has been taken into account high temperature resistant, corrosion-resistant, the anti abrasive performance requriements of sealing member and the low market requirement of production cost.Thereby both can satisfy the sealing property of sealing member, increase the service life, can reduce the sealing cost again, improve the ratio of performance to price.
