摘要： A method for improving the toughness of the surface of a ceramics product, characterized in that the ceramics product is substituted to a plastic working wherein a dislocated structure is formed in the sub-surface regions thereof, the structure being in a straight line form and covering uniformly over the whole of the ceramics product and having a dislocation density of 1×104 to 9×1013 cm−2, by the use of a jet material comprising fine particles having a convexly curved surface and having an average particle size of 0.1 μm to 250 μm and a Vickers hardness (HV) of 500 or more and of a hardness (HV) of the ceramics products +50 or less; and ceramics products which have a dislocated structure being in a straight line form and covering uniformly over the whole of the surface thereof and having a dislocation density of 1×104 to 9×1013 cm−2.

摘要： A ceramics sintered material cutting tool, characterizing in that it has a dislocation structure which formed on the surface thereof in a straight line from and distributed uniformity in a dislocation density of 1×104 to 9×1013 cm−2. The cutting tool is improved in a fracture toughness value and the resistance to thermal shock and thus has a prolonged life. The above cutting tools include, in particular, a twist drill and a throw away tip.
