全自動洛(luo)氏(shi)硬(ying)(ying)度計(ji)(ji)是一(yi)種(zhong)常見的硬(ying)(ying)度測(ce)(ce)(ce)試(shi)儀器，它通(tong)過(guo)測(ce)(ce)(ce)量(liang)材(cai)(cai)料在受(shou)到一(yi)定(ding)(ding)載(zai)荷(he)作(zuo)(zuo)用下(xia)的壓(ya)(ya)痕(hen)(hen)尺寸來確(que)定(ding)(ding)材(cai)(cai)料的硬(ying)(ying)度。其工作(zuo)(zuo)原(yuan)理主要包(bao)括以下(xia)幾個步(bu)驟(zou)：1.選擇適當(dang)的測(ce)(ce)(ce)試(shi)力(li)(li)(li)：根據待(dai)(dai)測(ce)(ce)(ce)試(shi)材(cai)(cai)料的硬(ying)(ying)度范(fan)圍，選擇相應的測(ce)(ce)(ce)試(shi)力(li)(li)(li)。通(tong)常使用的測(ce)(ce)(ce)試(shi)力(li)(li)(li)有3kgf、10kgf、30kgf等。2.加(jia)(jia)載(zai)測(ce)(ce)(ce)試(shi)力(li)(li)(li)：將選定(ding)(ding)的測(ce)(ce)(ce)試(shi)力(li)(li)(li)加(jia)(jia)載(zai)到硬(ying)(ying)度計(ji)(ji)的機械系(xi)統中。對于(yu)全自動洛(luo)氏(shi)硬(ying)(ying)度計(ji)(ji)，這(zhe)一(yi)步(bu)通(tong)常由電機或(huo)液壓(ya)(ya)系(xi)統完成。3.制(zhi)動進(jin)樣：在加(jia)(jia)載(zai)測(ce)(ce)(ce)試(shi)力(li)(li)(li)的同時(shi)，制(zhi)動系(xi)統將非常小的壓(ya)(ya)頭推(tui)向(xiang)待(dai)(dai)測(ce)(ce)(ce)試(shi)材(cai)(cai)料表(biao)面(mian)，產(chan)生一(yi)個準(zhun)備進(jin)行壓(ya)(ya)痕(hen)(hen)的初始接觸。4.進(jin)行壓(ya)(ya)痕(hen)(hen)：一(yi)旦測(ce)(ce)(ce)試(shi)力(li)(li)(li)加(jia)(jia)載(zai)到位并且接觸到位，系(xi)統會繼續施加(jia)(jia)恒定(ding)(ding)的壓(ya)(ya)力(li)(li)(li)在材(cai)(cai)料表(biao)面(mian)上，形成一(yi)個壓(ya)(ya)痕(hen)(hen)。壓(ya)(ya)載(zai)時(shi)間一(yi)般為10-15秒。廣(guang)東布(bu)氏(shi)硬(ying)(ying)度計(ji)(ji)怎么(me)測(ce)(ce)(ce)試(shi)
