摘要： PROBLEM TO BE SOLVED: To provide a technology which sprays a thermal spraying air current to droplets to give good thermal spraying in an arc type thermal spraying device. SOLUTION: A thermal spraying device 10 is provided with a moving mechanism which moves a plurality of wiry thermal spraying materials to a position where the tips of the spraying materials are adjacent to each other, an energizing mechanism which gives potential differences between a plurality of the wiry thermal spraying materials, a droplet stretching air current blowing mechanism which blows an air current for stretching the droplets formed in the vicinity of the tips of the thermal spraying materials, and a thermal spraying air current jetting mechanism which jets an air current that scatters to a thermal spraying surface, the droplets in the vicinity of the tips of the droplets stretched by the air current which the droplet stretching air current flowing mechanism blows. The droplet stretching air current blowing mechanism stretches the droplets, and the thermal spraying air current scatters the vicinities of the tips of the droplets thus stretched, and consequently, the thermal spraying air current does not get in direct contact with the position in the vicinity of the spraying materials, and an arc is stably generated to give good thermal spraying.

摘要： PROBLEM TO BE SOLVED: To heighten the synchronization of a roller die so as to provide good form rolling for an article to be machined by providing a torque control means for equalizing one torque to another by comparing the detection results of both torque detecting means with each other. SOLUTION: Each torque is calculated based on the torque signals of first and second torque sensors 58 and 59. If a difference is positive, since the torque of a first constant velocity joint 53 for transmitting a driving force to a first roller die 32 is large, an instruction for adjusting the torque transmission factor of a first variable clutch 52s is outputted to the drive circuit of the first variable clutch 52s so as to equalize one torque to another. If a difference is negative, since the torque of a second constant velocity joint 56 is large, an instruction for adjusting the torque transmission factor of a second variable clutch 55s is outputted to the drive circuit of the second variable clutch 55s so as to equalize one torque to another.

摘要： PROBLEM TO BE SOLVED: To enable roll forming with high precision by applying to the surface of a die a lubricant selected in accordance with the temperature of the surface of the die. SOLUTION: Hot or warm roll forming is performed by a roller die 1. The surface temperature of the roller die (roll forming die) 11 is measured by a radiation thermometer during roll forming. In accordance with that surface temperature, a lubricant is applied to the surface of the die 1 from an injecting nozzle 6 using a controller 3 and a control unit 4. At least one kind of lubricant is selected from the lubricants A, B, C inside plural tanks 5a-5c and sent to the injecting nozzle 6 through a stop valve. The lubricants to be used are water- soluble type with a solid lubricant such as graphite particles or BN fine particles dispersed in a solvent like water, emulsion type with an oil solvent partially mixed, or these types with an addition of alcohols. Thus, a stable lubricating effect is obtained.

摘要： PURPOSE:To increase the porosity in a ceramic layer and to improve its thermal cycle resistance, at the time of thermal-spraying ceramics on the surface of a base metal, by spraying a liquid for cooling on a molten thermal spraying body directly upon the surface of the base metal. CONSTITUTION:The surface of a base metal 3 such as Al to be treated is subjected to shot blasting treatment and is roughened. Next, this surface is plasma sprayed with the powder, e.g. of an Ni-Cr-Al, series alloy to form an intermediate layer. After that, the powder, e.g. of ZrO2.8Y2O3) is simultaneously plasma-sprayed on the above intermediate layer by a thermal spraying gun 1 to form a ceramic thermal spraying layer 6 At this time, simultaneously, by spraying water droplets 4 having 1 to 20mum diameter on the ceramic thermal spraying layer 6 in a molten state by a mist spray 2, porosity in the ceramic sprayed deposit is increased to form the ceramic thermal spraying layer 6 excellent in thermal cycle resistance.

摘要： PURPOSE:To improve machined property even under a high temperature by providing a coating layer which is flame-coated at a portion near a moving element for a fixing member, contains 10vol% or more ceria and has the face machined and created by the moving element. CONSTITUTION:A coat layer 85 is provided which is flame-coated at a portion P near a turbo rotor 82 for a turbo housing 81, contains 10vol% or more ceria and has the face machined and created by the turbo rotor 82. As a result, the machined property can be made excellent even under a high temperature. The turbo rotor 82 is therefore hard to be damaged and even when it is used under a high temperature for a long time, the coating layer 85 is prevented from separation, falling or corrosion, so that a gap between the turbo rotor 82 and the turbo housing 81 can be brought rear to zero.
