根據(jù)里氏原理，只要材料具備一定剛性，能形成反彈，就能測出準(zhǔn)確的里氏硬度值，但很多材料里氏與其它制式的硬度沒有相應(yīng)的換算關(guān)系，因此里氏硬度計(jì)目前只裝了9種材料的換算表。具體材料如下：鋼和鑄鋼，合金工具鋼，灰鑄鐵，球墨鑄鐵，鑄鋁合金，銅鋅合金，銅錫合金，純銅，不銹銅。

According to the Richter principle, as long as the material has a certain rigidity and can form a rebound, the exact value of the Richter hardness can be measured, but there is no corresponding conversion relationship between the Richter hardness of many materials and the other forms, so the Richter hardness meter currently only contains the conversion tables of 9 materials. Specific materials are as follows: steel and cast steel, alloy tool steel, gray iron, ductile iron, cast aluminum alloy, copper zinc alloy, copper tin alloy, pure copper, stainless copper.

對于一些特殊材料的試樣，用戶可使用公司提供的擬合曲線軟件做專用換算表。在實(shí)際生產(chǎn)中，使用的金屬材料多種多樣，由于里氏硬度計(jì)對材料的加工方式、 材料的合金元素組成敏感，而里氏硬度計(jì)芯片中儲(chǔ)存的硬度換算表不可能都滿足用戶的需要，用戶在測試中，可以使用擬合軟件做自己專用的硬度換算表。

For some special materials, users can use the fitting curve software provided by the company to make a special conversion table. In actual production, there are various kinds of metal materials used, because the Richter hardness meter is sensitive to the processing mode of material and the composition of the alloy elements of the material, and the hardness conversion table stored in the chip of the Richter hardness meter can not meet the needs of the user. In the test, the fitting software can be used to make its own special hardness. Conversion form.

二、 基本原理

Two. Basic principles

里氏硬度計(jì)基本原理是具有一定質(zhì)量的沖擊體在一定的試驗(yàn)力作用下沖擊試樣表面，測量沖擊體距試樣表面1mm 處的沖擊速度與回跳速度，利用電磁原理，感應(yīng)出與速度成正比的電壓。里氏硬度值以沖擊體回跳速度與沖擊速度之比來表示，較硬的材料產(chǎn)生的反彈速度大于較軟者。

The basic principle of the hardness meter is that the impact body with a certain quality impact the surface of the specimen under certain experimental force, and measures the impact velocity and the rebound velocity at the 1mm of the specimen surface, and uses the electromagnetic principle to induce the voltage that is proportional to the velocity. The Ricky hardness is represented by the ratio of impact velocity to impact velocity, and the rebound velocity of harder material is greater than that of the softer.
