Abstract

PURPOSE:To obtain a tool which is excellent in heat resistance, shock resistance, and wear resistance by mixing the three ingredients of Si3N4, TiN, and sintering auxiliaries consisting of a mixture of AIN and Al2O3, within a certain scope in a specific triangular coordinate, and sintering them. CONSTITUTION:Using a triangular coordinate indicating the wt% of Si3N4, TiN, and sintering auxiliaries consisting of a mixture in which the ratio of one kind or the mixture of Y2O3 and Dy2O3 to the mixture of AIN and Al2 containing 5 5-60% AIN is 3/1-1/3, the three ingredients mentioned above are mixed. In other word, the three ingredients are mixed in a scope surrounded by lines connecing a point A (84wt% Si3N4, 5wt% TiN, and 11wt% sintering auxiliaries), a point B (55wt% Si3N4, 5wt% TiN, and 40wt% sintering auxiliaries) and a point C (55wt% Si3N4, 34wt% TiN, and 11wt% sintering auxiliaries). And, by molding this mixture and sintering it at 1,550-1,750 deg.C in a non-oxidizing atmosphere, a desired nitride group ceramic tool can be obtained.

．シやすくなり、高速切削に耐えなくなる。Here, St3% is the main component, and α type is suitable as the starting material, and the particle size is preferably 2μ or less. TiN also improves the toughness of S13N4 and has the effect of preventing crater wear when used as a cutting tool, as is known. If it is less than 5%, there is little effect. As a result of investigating the relationship between the coefficient of expansion and thermal shock resistance through various cutting experiments, it was found that if the coefficient of thermal expansion exceeds 5X10'/°C, it deteriorates, so the amount of TiN was determined to be the corresponding amount, that is, 34% or less. Next, the sintering aid is intended to improve sintering properties and enable the cold press method that can be industrially mass-produced, and also to improve the wear resistance of Sis Ntt and TiN, which are inherently easy to wear. This is what I did. If it is less than 11%, the wear resistance is poor and at the same time sintering is difficult, requiring real pressing. If it exceeds 40%, it will soften at high temperatures'1
．． It becomes easy to cut and cannot withstand high-speed cutting.

い。The reason why we limited the ratio of the mixture of AIN and Al2O containing 5 to 60% of Y2O, oy2o3 and AIN to 3/1 to 1/3 is that this range is the most sinterable composition and at the same time This is because the strength of the structure is high. AIN and A1.
The reason why AIN was limited to 5 to 60% in the mixture of L03 was to increase hardness without reducing strength; less than 5% would have little effect, and more than 60% would reduce strength. . The ceramic plate for tools of the present invention can be obtained by pulverizing and mixing the above raw materials using a ball mill or the like, molding, and then sintering. Sintering temperature is 1550℃~
1750'j: is suitable; below 1550°C, no sintering occurs, and above 1750°C, the 5taN+ component volatilizes violently and foams. Of course, it can be manufactured by the hot press method or the HIP method, but it is difficult to mass-produce it industrially.
