Ceramic gauge block and the test methods
The amount of the block on the manufacture, test, precision, have certain requirements for the use of bearing steel and cemented carbide with GCrl5 steel gauge block made of metal is more widely used, their manufacture and use of the situation is more mature, it has the metal materials features, performance, stability, easy processing, low cost, wide range of applications. The new ceramic materials with a ceramic gauge block is known. Production of ceramic gauge block of ceramic material is zirconia (ZrOz) ceramic, zirconia ceramic of density, hardness,[link widoczny dla zalogowanych], mechanical properties,[link widoczny dla zalogowanych], especially the flexural strength and fracture toughness of high volume precision manufacturing with the basic block material characteristics, can be used to ensure product reliability and safety. Manufacture of ceramic gauge block grinding method used, the amount in the ceramic block can be formed on the surface pressure of fin layer, the amount of block increased surface strength. As zirconia ceramic (ZrO) has superior performance, in addition to making the amount of blocks, its broad range of applications. Zirconia ceramic can be used as wear and corrosion resistance components, such as chemical industry mud pump seals, blades and pump, mining, industrial bearings,[link widoczny dla zalogowanych], also be used as molds, cutting tools, nozzles, insulation parts, rocket and jet engine wear, corrosion engineering nuclear reactor parts and high temperature structural materials. Since zirconia (ZrO) hardness of ceramic materials, production volume of the block and the sealing gasket and other parts of simple shape, because of the difficulty of processing small, high value-added products, applied more widely. For complex parts due to processing more difficult, the application is not currently very common ceramic gauge block, compared with the metal content of the block has the following advantages (1) manufacturing corrosion resistance of zirconia ceramic gauge block water, oil, not afraid of acid, alkali (unless strong acid, alkali). Typically, no special cleaning, apply anti-rust oil. Storage, very convenient. (2) wear resistance of ceramic gauge block the manufacture of high hardness, wear resistance, compared with the metal content of the block in the same paradox of the load, under the same grinding conditions. The amount of metal wear is only one-tenth of the block; Therefore, ceramic gauge blocks are very wearable, and not prone to scratches. (3) dimensional stability 11rj7m {used in the manufacture of ceramic gauge block precision zirconia ceramic material has the characteristics of materials stability; Therefore, the amount of such material block size, good stability, test period and metal content of the block can be extended compared to the corresponding measured values of stability. (4) identify a clear white color of ceramic gauge block,[link widoczny dla zalogowanych], the amount of block number, nominal size and other logos are laser engraved, black, black and white, contrast, beautiful appearance, feel good, make the user feel pleasant mood I am happy 2 Detection of the production of 8l2, 8l-3 and other specifications of the ceramic gauge blocks, gauge block reference to the manufacture of some foreign standards, such as the U.S. Federal Specification GGGG a 1sc and so on. As the amount of the block is a high precision measuring instruments, the measurement method, the accuracy of measurements, a direct impact on the quality of new products. At present, our production of ceramic gauge block inspection methods of comparative measurements, the prosecution Chau steel base metal is used in mass production of ceramic gauge block, then the oxidation of (ZrO:) ceramic materials, the linear expansion coefficient of whooping _ a (10 Soil 1) × 10 Canton C,[link widoczny dla zalogowanych], while the linear expansion coefficient of steel materials, one (11.5 Soil 1) X10 / ℃, so that ceramic material and metal according to the linear expansion coefficient difference between the material and temperature changes, correction of the test data to ensure that the amount of the block of ceramic products, the accuracy and reliability of measurement data. Used as a test base of the steel gauge blocks, measured by light interferometry on a regular basis to ensure the accuracy of their money in order to ensure product quality ceramic gauge block. 3 Summary of the ceramic gauge block with excellent performance, along with its co-wow to good research, and research efforts, it is not conductive and not magnetic, its use will be more widely addition, the linear expansion coefficient of the block and metal steel quality linear expansion coefficient similar. To use and great convenience product swaps. A great amount of metal to replace the momentum of the block; Therefore, domestic production of ceramic gauge block manufacturers with reference to the metal content of the block group sets, levels, such as the production of ceramic gauge block size, it is easy to product updates, money transfer is also soft for easy reference Documents 1 Zhou Yu.
