摘要： A ceramic body having a surface region containing tetragonal zirconia is sintered to at least 95% theoretical density at a temperature below about 1550 .degree. C. The surface region is then heat treated to reverse local stresses therein. Low temperature degradation in tetragonal zirconia, and materials containing tetragonal zirconia, is significantly inhibited. The heat treated ceramic is especially suited for use in structural components such as valves, engine housings, pistons (chambers) and the like which, during operation, are frequently exposed to temperatures ranging from room temperature to 500.degree. C. for prolonged periods of time.

摘要： A ceramic circuit substrate providing a circuit pattern with a fine line as well as high accuracy for positioning the circuit pattern and a method of producing the ceramic circuit substrate. An alumina layer that is green containing an alumina that is not sintered at a temperature ranging from 800.degree. to 1000.degree. C. is applied on a surface of a ceramic green sheet containing glass and then fired at a temperature ranging from 800.degree. to 1000.degree. C. The ceramic green sheet is sintered into a sintered ceramic substrate. A porous alumina layer is formed on a surface of the sintered ceramic substrate. The glass contained in the sintered ceramic substrate is caused to flow to the inside of the porous alumina layer so that the part of the porous alumina layer filled with the glass is bonded to the sintered ceramic substrate. The part of the porous alumina layer not filled with the glass is removed, wherein the porous alumina layer remaining on the sintered ceramic substrate after the removing has a thickness of 10 .mu.m or less. A paste for forming the circuit pattern is printed on a surface of the part of the porous alumina layer that has been bonded to the sintered ceramic substrate for heating.

摘要： Surface modification of magnetic recording heads using plasma immersion ion implantation and deposition is disclosed. This method may be carried out using a vacuum arc deposition system with a metallic or carbon cathode. By operating a plasma gun in a long-pulse mode and biasing the substrate holder with short pulses of a high negative voltage, direct ion implantation, recoil implantation, and surface deposition are combined to modify the near-surface regions of the head or substrate in processing times which may be less than 5 min. The modified regions are atomically mixed into the substrate. This surface modification improves the surface smoothness and hardness and enhances the tribological characteristics under conditions of contact-start-stop and continuous sliding. These results are obtained while maintaining original tolerances.

The fixture includes a housing having first and second end walls connected between first and second side walls wherein the first and second end and side walls form an interior aperture. In addition, the fixture includes a several slots which are formed in the first and second side walls wherein each of the slots are suitable for holding a single masking element. In particular, the interior aperture is of a sufficient size and the slots are positioned such that suitable air circulation is provided between each of the masking elements to expose the masking elements to a predetermined temperature suitable for removing the impurities from the masking elements. Furthermore, the fixture includes openings formed in the end walls which enable handling of the fixture and provide additional air circulation.
