摘要： PURPOSE:To obtain the forming die having high accuracy and strength, and also, having a long service life by forming a mixing layer formed on the surface of the forming die for abutting on a work by the relation of a prescribed expression. CONSTITUTION:A mixing layer is formed on the surface of a forming die by executing simultaneously implantation of an ion and vacuum vapor deposition by the relation of an expression 10X ) of the ion, and the vapor deposition quantity (vapor deposition speed ; Angstrom /sic) of a metallic element, respectively, and accordingly, a surface layer being excellent in wear resistance can be provided. Moreover, on its surface layer, a metal or an intermetallic compound by the ion is formed by being brought to mixing integrally with a material substrate, therefore, a die of high strength in which the surface layer does not peel off even under a severe dynamic pressure condition.

摘要： PURPOSE:To predict a proper time when bits are to be replaced by mounting a radiative member at least one spot of an excavation bit comprising a cemented carbide or a ceramic-made chip. CONSTITUTION:Chips 3 are laterally implanted into a bit main body 2 in the upstream of an advancing direction side by side while chips 4 are laterally implanted side by side on the downstream side. A detection member 5 made of a radiative member is mounted to each hip 3, thereby constituting a bit 1 fitted with a wear detection performance. The radiation in the excavated earth and sand is detected by driving a shield drilling machine to which the bit 1 is mounted. If no radiation is detected from the earth and sand, the bit 1 is considered to be not affected by damages, such as wear, defect, cracks and be serviceable, remaining in its original shape. On the other hand, if radiation is detected in the excavated earth and sand, the degree of the damage of the bit at the tip will be predictable by its dosage, which makes it possible to carry out predict control of the lifetime of the bit.

摘要： PURPOSE:To increase the strength of an edge section, and to deal with severe service conditions for a prolonged time by previously forming a recessed section in the base metal surface, on which a padding layer is formed, implanting a cemented tip into the recessed section and forming a curing padding layer through padding from the upper section of the tip. CONSTITUTION:A groove 4a for implanting a tip 5 is formed along the outer circumference of a wedge-shaped sectional edge section 4, and the cemented tip 5 is implanted. When a curing padding layer 7 is formed annularly extending over the whole circumference on an inclined face slightly nearer than the exposed section of the tip 5 to a center, a button-shaped cemented tip 10 for reinforcement is implanted into the recessed section 9 of the curing padding layer 7, and the curing padding material 7 is padded onto the surface of a base metal 2 including the cemented tip 10. A fitting hole 3 is bored at the core section of the circular base metal 2 made of steel, and an edge section 4 is fitted to an outer circumferential section. Accordingly, the curing padding layer 7 is reinforced by the cemented tip 10 having high strength, thus largely improving abrasion resistance.

摘要： PURPOSE:To obtain the forming die having high accuracy and a long service life by executing simultaneously ion implantation and vacuum deposition to the surface on which an object to be worked abuts, and forming a mixing layer provided with an amorphous metallic layer. CONSTITUTION:Ion implantation and vacuum deposition are executed simultaneously to the surface 4 on which at least an object to be worked for forming abuts of the upper and the lower dies 1, 2. As a result, a mixing layer provided with an amorphous metallic layer is formed on the forming dies 1, 2. The mixing layer is formed by implantation of an N ion and vapor deposition of Ti. In such a way, the surface layer being excellent in wear resistance can be provided on the die.
