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 is a problem that handling is extremely complicated, for example, storage must be carried out in a completely corrosion-proof environment, and corrosion-proof gloves must be worn at all times when handling. Further, when corrosion occurs, the surface condition of the surface for indicating dimensions is damaged, resulting in problems such as not being able to secure correct dimensions, or not being able to achieve so-called ringing, which means that the gauge cannot be brought 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Ｃｒによ

たすべくなされたものである。This invention was made in view of the above circumstances, and the block gauge is formed using a corrosion-resistant material, and in addition, the block gauge has material homogeneity, wear resistance, ease of handling, This was done to meet all the requirements for marking such as nominal dimensions.

る。[Means and effects for solving the problem] Thus, the inventor of this invention first studied 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. We selected the material that satisfies the requirements and invented a processing method that is suitable for the selected corrosion-resistant material.
Completion was achieved based on that processing.

The part of the ceramic to be marked is kept in an inert gas atmosphere or under reduced pressure, and a laser beam is applied to the part to be marked. It is a block gauge that is marked by irradiating it.

保されたものとなっている。That is, the inventor selected ceramics because it is a corrosion-resistant material and has homogeneity. Furthermore, when using a block gauge, it is white or light yellow because it contrasts with the surroundings of the site and is easy to see, and it has sufficient wear resistance.
Furthermore, since the object 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 is the homogeneity of a dense structure, and after sintering, As a ceramic that satisfies the fact that no volume change occurs,
Zirconium oxide ZrO* is the main component, and 7. A zirconia ceramic body was used as a material by sintering 20 g of yttrium oxide Y in a weight ratio of 3 to 7% by weight to rOt and an auxiliary agent of aluminum oxide Al201 in a weight ratio of 0 to 20% by weight. In addition, by using the above ingredients, the resulting zirconia ceramic becomes a mixed phase of cubic and monoclinic crystals, a so-called partially stabilized state, which provides high strength and toughness, ensuring brittle resistance. It has become something that has been done.

光を照射することによって解決した。In addition, the marks to be applied to the block gauge, such as nominal dimensions, product numbers, trademarks, etc., are preferably black because the zirconia ceramic body is white or light cream color, and provides a high contrast with this color, and also allows for ringing. In order to achieve this, it is necessary to form the ringing surface 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 with respect to the ringing surface by placing the part to be marked in an inert gas atmosphere or under reduced pressure and irradiating it with laser light. .

Furthermore, the inert gas atmosphere specifically refers to spraying the inert gas onto the marking surface of the zirconia ceramics, or placing the zirconia ceramics in a sealed chamber and then flowing the inert gas into the sealed chamber. obtained by

The output of the device is IOW, the frequency is 8 KHz, the moving speed of the laser beam irradiation point is 22 mm/sec, and the laser beam is irradiated in Q-switch mode to mark the nominal dimensions, product number, and trademark. was carried out.

ていて寸法上の変化は全くと言ってよいほどない。The zirconia block gauge obtained by the above-mentioned process is made of zirconia ceramics and does not corrode, which eliminates handling problems such as storing it under corrosion-resistant conditions or wearing corrosion-resistant gloves, and it also has homogeneity. However, there is almost no dimensional change at all.

クはそのまま保たれ何の変化も生じなかった。Further, by irradiating the laser beam 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 color of the base, making it easy to read the contents of the mark. In addition, marking by the above method did not cause protrusions to be formed on each surface of the zirconia block gauge and the flatness was maintained, so there was no problem in adhering it to other zirconia block gauges. . 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.
ジルコニアブロックゲージの熱膨張係数を測定したとこ
ろ、約１０ Ｘ １０−’／’Ｃであった。因に鋼の熱
膨張係数は、約１１．５ Ｘ １０−’／”Ｃである。When the thermal expansion coefficient of the zirconia block gauge was measured, it was approximately 10 x 10-'/'C. Incidentally, the coefficient of thermal expansion of steel is approximately 11.5 x 10-'/''C.
従って、使用環境の温度が変化した際、被測定物が鋼製

ジの熱膨張が近似的に追従し、温度変化によって大きな
誤差が生じるということはない。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, causing a large error due to temperature changes. There isn't.

確保されていることになる。A wear resistance test was conducted in which a zirconia block gauge was placed on an FC surface plate (cast iron plate) and moved in planetary motion at a speed of 260 cm/min while applying a constant load and with a friction distance of 8000 m. As a result, it was about 0.
Abrasion of 0.07 μm was observed. Incidentally, in a wear resistance test under the same conditions, steel had a wear resistance of about 0. Abrasion of 7 μm was observed in the case of the super steel, and wear of approximately 0.25 μm was observed in the case of the super steel. In other words, the zirconia block gauge is about 10
This means that the wear resistance is approximately 3.5 times that of cemented carbide.

In addition, the material is homogeneous, so there are almost no errors in dimensions, and both abrasion resistance and brittleness are ensured, and the white or pale yellow base makes it easy to stand against the surroundings. The markings are black and have good contrast against the background, and the coefficient of thermal expansion is close to that of steel, so if the object to be measured is made of steel, errors due to temperature changes can be minimized. ing.
