題が生じる。[Problems to be Solved by the Invention] Block gauges made of metal materials are not completely corrosion resistant and are prone to corrosion. For this reason, there are problems in that handling is extremely complicated, for example, storage must be carried out in a completely corrosion-resistant environment, and corrosion-resistant gloves must be worn at all times when handling. Further, when corrosion occurs, the surface condition of the surface used to indicate dimensions is damaged, causing problems such as the inability to secure correct dimensions, and the inability to achieve so-called ringing, which allows the block gauge to come into close contact with other block gauges.
尚、耐蝕性を増加させるために、例えばクロム

It is conceivable to plate it with Cr.
However, plated block gauges have problems in that the number of manufacturing steps is increased, and it is difficult to obtain a predetermined nominal size, making manufacturing complicated.

ある。[Means and effects for solving the problem] Thus, the inventor of the present invention first investigated a plurality of corrosion-resistant materials in order to solve the problem of corrosion resistance, and selected from among them all the requirements for a block gauge. This was achieved by selecting a material that satisfies the requirements, inventing a processing method suitable for the selected corrosion-resistant material, and applying that processing.

ものとなつている。 That is, the inventor selected ceramics because it is a corrosion-resistant material and has homogeneity. In addition, the color of the block gauge is white or light yellow because it contrasts with the surroundings of the site where it is used and is easy to see.
In addition, sufficient wear resistance is ensured, and since the target of comparison measurement is mainly steel, it has a thermal expansion coefficient almost equal to that of steel, and in addition, the homogeneity of the material has a dense structure. The main component is zirconium oxide, ZrO 2 , as a ceramic that is durable and does not change in volume even after sintering.
A zirconia ceramic body is made by sintering yttrium oxide Y 2 O 3 with a weight ratio of 3 to 7% by weight and aluminum oxide Al 2 O 3 of 0 to 20% by weight as an auxiliary agent to ZrO 2 as the main component. And so. In addition, by using the above ingredients, the resulting zirconia ceramics will be in a mixed phase state of cubic and monoclinic crystals, a so-called partially stabilized state, resulting in high strength and toughness, ensuring brittle resistance. It has become something that has been done.

性ガスを流込むことによつて得られる。 In addition, the marks to be placed on the block gauge such as nominal dimensions, product numbers, trademarks, etc. should be preferably black because the zirconia ceramic body has a white or light cream color and can provide a high contrast with this color, and ringing should be avoided. In order to be able to do so, it is necessary that the ring be formed at the same height or at a lower height than the ringing surface. However, the inventor solved the problem of the color of the mark and the height of the mark relative to the ringing surface by keeping the area to be marked in an inert gas atmosphere or under reduced pressure and irradiating it with laser light. Settled. Note that the inert gas is preferably nitrogen gas N 2 , helium He, argon Ar, or a mixed gas thereof. In addition, the inert gas atmosphere specifically refers to blowing the inert gas onto the marking surface of the zirconia ceramics, or placing the zirconia ceramics in a sealed chamber and then pouring the inert gas into the sealed chamber. obtained by

た。 Finally, while spraying N 2 gas at a pressure of approximately 0.40 kg/cm 2 at an angle of 30 to 60 degrees from the N 2 gas nozzle at a distance of 3 cm, the YAG laser is applied to the surface of the shaped zirconia ceramic to be marked. The output of the generator is 10W, the frequency is 8KHz, the moving speed of the laser beam irradiation point is 22mm/sec, and the laser beam is irradiated in Q switch mode to mark the nominal dimensions, product number, and trademark. I did this.

は全くと言つてよいほどない。 The zirconia block gauge obtained by the above-mentioned process is made of zirconia ceramics and does not corrode, so problems in handling such as storing it under corrosion-resistant conditions or wearing corrosion-resistant gloves can be solved, and it also has good homogeneity. It can be said that there is almost no dimensional change.
ジルコニアブロツクゲージは乳白色であつて使

かつた。 Further, by laser beam irradiation under specific conditions, a black mark with a slightly depressed groove shape can be obtained. Therefore, the mark has sufficient contrast against the milky white background, making it easy to read the contents of the mark. In addition, marking by the above method does not form protrusions on each surface of the zirconia block cage and maintains its flatness, so there is no problem in adhering it to other zirconia block cages. . Although the mark was subjected to a light resistance test (equivalent to 10 years) using a carbon arc lamp, the mark remained as it was and no change occurred.

ツクゲージの熱膨張が近似的に追従し、温度変化
によつて大きな誤差が生じるということはない。 When the thermal expansion coefficient of the zirconia block gauge was measured, it was approximately 10×10 -6 /°C. Incidentally, the thermal expansion coefficient of steel is approximately 11.5×10 -6 /°C. Therefore, when the temperature of the usage environment changes, if the object to be measured is made of steel, the thermal expansion of the zirconia block gauge will approximately follow the thermal expansion of the object to be measured, and large errors will occur due to temperature changes. It never happens.

It was placed in planetary motion at a speed of 260cm/min while applying a constant load, and the friction distance was 8000m.
When a wear resistance test was carried out by moving the product as an object, approximately 0.07 μm of wear was observed. Incidentally,
In a wear resistance test under the same conditions, steel has approximately
Abrasion of 0.7 μm was observed, and wear of approximately 0.25 μm was observed for the super steel. In other words, zirconia block gauges have about 10 times the wear resistance of steel, and about 3.5 times the wear resistance of super steel.
