化タングステン及び炭化チタンを主成分とした合金が使
用されて来た。Detailed Description of the Invention The present invention relates to materials with high wear resistance and corrosion resistance. Conventionally, alloys mainly composed of tungsten carbide and titanium carbide have been used as sliding materials with high hardness and excellent corrosion resistance. It's here.
しかるに炭化タングステンを主成分としたものは経済的
に高価なものとなってきたため一般的なシールリング等
の摺動材料としての使用が難かしくなってきたし、又こ
のものでは耐摩耗性、耐食性にも限界があった。However, tungsten carbide as a main component has become economically expensive, making it difficult to use as a sliding material for general seal rings, etc., and it has poor wear resistance and corrosion resistance. There were also limits.
一方炭化チタンを主成分としたものは耐熱特性が低いと
いう欠点があった。On the other hand, those containing titanium carbide as a main component have a drawback of low heat resistance.
本願発明では上述の諸欠点を解消する材料を提供せんと

４０Ｖｏｌ％含有する組成からなる耐摩耗、耐食性を有
する摺動材料である。The present invention aims to provide a material that eliminates the above-mentioned drawbacks, and its gist is that it contains 5 to 50 Vol% of one or more of titanium carbide or tungsten carbide, with the balance being niobium carbide of 60 to 95 Vol%. , one or more iron group elements and one or more Mo, W, Ta in total of 5~
It is a sliding material having wear resistance and corrosion resistance and having a composition containing 40 Vol%.
以下本願発明を開発するについて行なった試験並びにそ
の結果を示す。Tests conducted to develop the present invention and their results are shown below.

度並びに比重、抗折力なそれぞれ示す。Table 1 shows the conventionally used alloys mainly composed of tungsten carbide or titanium carbide and the alloys (1) to (7) which are the compounding components of the hard alloy according to the present invention, by the normal manufacturing method of cemented carbide, that is, a ball mill. After mixing for 72 hours and adding 4 vol% of paraffin as a lubricant, 1500 kg/
After compression molding and preliminary sintering at cm2, each size is 1300~1
The hardness, specific gravity, and transverse rupture strength, which indicate the wear resistance of the alloys sintered at 450°C, are shown.

焼結によって固溶体を作りそれ自身耐摩耗性を有し、耐
食性も向上するが５Ｖｏｌ％以下では焼結性が劣化し耐
摩耗性が下がり５０Ｖｏｌ％を超えると耐食性が悪くな
る。When niobium carbide in the present invention contains 5 to 50 Vol% of one or both of titanium carbide or tungsten carbide, a solid solution is formed by sintering, which itself has wear resistance and improves corrosion resistance, but if the niobium carbide is less than 5 Vol%, sintering is deteriorated and wear resistance decreases, and if it exceeds 50 Vol%, corrosion resistance deteriorates.
またこれらが６０Ｖｏｌ％以下でな耐摩耗性、耐食性が
劣化し、９５Ｖｏｌ％を越えると合金の強度が低下して
実用上使用できない。Furthermore, if the content is less than 60 Vol%, the wear resistance and corrosion resistance will deteriorate, and if it exceeds 95 Vol%, the strength of the alloy will decrease and it cannot be used practically.
鉄族元素すなわち鉄、ニッケル、コバルトの一種又は二

低下し、４０Ｖｏｌ％を越えると耐摩耗性、耐食性が劣
化する、この様に該バインダーにＭｏ、Ｗ、Ｔａを含有
させるのは濡れ性の改善を図り焼結性が良く緻密な材料
を得る為である。One or more of iron group elements, i.e., iron, nickel, and cobalt, and one or more of Mo, W, and Ta are used as binders, but if the amount is less than 5 vol%, the strength will decrease, and if it exceeds 40 vol%, the strength will decrease. The purpose of including Mo, W, and Ta in the binder, which deteriorates wear resistance and corrosion resistance, is to improve wettability and obtain a dense material with good sinterability.
以上の試験結果により本願発明材料は超硬合金に比べる
と抗折力は幾分低いが硬度は大であるので、耐摩耗性に
優れており、耐食性の点でも超硬合金のそれよりも（特
に対Ｈ２ＳＯ４につき）優れている。The above test results show that the material of the present invention has a somewhat lower transverse rupture strength than cemented carbide, but has a higher hardness, so it has excellent wear resistance and is better than cemented carbide in terms of corrosion resistance. It is particularly excellent against H2SO4.
又炭化チタンを主成分とする合金よりも耐熱性、耐食性
の双方において優れている。Furthermore, it is superior to alloys whose main component is titanium carbide in both heat resistance and corrosion resistance.
従って本願発明材料はシールリング材をはじめとする摺
動材料として有用なものである。Therefore, the material of the present invention is useful as a sliding material such as a seal ring material.
