家裝不銹鋼管
家(jia)(jia)裝(zhuang)不(bu)銹(xiu)(xiu)鋼管(guan)(guan)(guan)一般常用布(bu)氏(shi)(shi)(shi)(shi)(shi)、洛(luo)氏(shi)(shi)(shi)(shi)(shi)、維(wei)(wei)(wei)氏(shi)(shi)(shi)(shi)(shi)三種硬(ying)(ying)(ying)(ying)(ying)度(du)(du)(du)(du)指標(biao)來衡量(liang)其硬(ying)(ying)(ying)(ying)(ying)度(du)(du)(du)(du)。 家(jia)(jia)裝(zhuang)不(bu)銹(xiu)(xiu)鋼管(guan)(guan)(guan)的(de)(de)(de)三種硬(ying)(ying)(ying)(ying)(ying)度(du)(du)(du)(du)： 洛(luo)氏(shi)(shi)(shi)(shi)(shi)硬(ying)(ying)(ying)(ying)(ying)度(du)(du)(du)(du)，家(jia)(jia)裝(zhuang)不(bu)銹(xiu)(xiu)鋼管(guan)(guan)(guan)洛(luo)氏(shi)(shi)(shi)(shi)(shi)硬(ying)(ying)(ying)(ying)(ying)度(du)(du)(du)(du)試(shi)驗(yan)同(tong)布(bu)氏(shi)(shi)(shi)(shi)(shi)硬(ying)(ying)(ying)(ying)(ying)度(du)(du)(du)(du)試(shi)驗(yan)一樣,都是(shi)(shi)(shi)壓痕試(shi)驗(yan)方法(fa)(fa)(fa)(fa)。不(bu)同(tong)的(de)(de)(de)是(shi)(shi)(shi),它是(shi)(shi)(shi)測量(liang)壓痕的(de)(de)(de)深(shen)度(du)(du)(du)(du),洛(luo)氏(shi)(shi)(shi)(shi)(shi)硬(ying)(ying)(ying)(ying)(ying)度(du)(du)(du)(du)試(shi)驗(yan)是(shi)(shi)(shi)當前應用很廣的(de)(de)(de)方法(fa)(fa)(fa)(fa),其中HRC在(zai)鋼管(guan)(guan)(guan)標(biao)準中使用僅次于(yu)(yu)布(bu)氏(shi)(shi)(shi)(shi)(shi)硬(ying)(ying)(ying)(ying)(ying)度(du)(du)(du)(du)HB,洛(luo)氏(shi)(shi)(shi)(shi)(shi)硬(ying)(ying)(ying)(ying)(ying)度(du)(du)(du)(du)可(ke)(ke)適用于(yu)(yu)測定由(you)極軟到極硬(ying)(ying)(ying)(ying)(ying)的(de)(de)(de)金(jin)屬材(cai)(cai)料,它彌補了(le)布(bu)氏(shi)(shi)(shi)(shi)(shi)法(fa)(fa)(fa)(fa)的(de)(de)(de)不(bu)是(shi)(shi)(shi),較(jiao)布(bu)氏(shi)(shi)(shi)(shi)(shi)法(fa)(fa)(fa)(fa)簡便(bian),可(ke)(ke)直接(jie)從硬(ying)(ying)(ying)(ying)(ying)度(du)(du)(du)(du)機的(de)(de)(de)表(biao)盤讀出硬(ying)(ying)(ying)(ying)(ying)度(du)(du)(du)(du)值(zhi)。但(dan)是(shi)(shi)(shi),由(you)于(yu)(yu)其壓痕小,故硬(ying)(ying)(ying)(ying)(ying)度(du)(du)(du)(du)值(zhi)不(bu)如布(bu)氏(shi)(shi)(shi)(shi)(shi)法(fa)(fa)(fa)(fa)準確。 布(bu)氏(shi)(shi)(shi)(shi)(shi)硬(ying)(ying)(ying)(ying)(ying)度(du)(du)(du)(du)，在(zai)家(jia)(jia)裝(zhuang)不(bu)銹(xiu)(xiu)鋼管(guan)(guan)(guan)標(biao)準中,布(bu)氏(shi)(shi)(shi)(shi)(shi)硬(ying)(ying)(ying)(ying)(ying)度(du)(du)(du)(du)用途最廣,往往以壓痕直徑來表(biao)示該材(cai)(cai)料的(de)(de)(de)硬(ying)(ying)(ying)(ying)(ying)度(du)(du)(du)(du),既直觀(guan),又方便(bian),但(dan)是(shi)(shi)(shi)對于(yu)(yu)較(jiao)硬(ying)(ying)(ying)(ying)(ying)的(de)(de)(de)或較(jiao)薄的(de)(de)(de)鋼材(cai)(cai)的(de)(de)(de)鋼管(guan)(guan)(guan)不(bu)適用。 維(wei)(wei)(wei)氏(shi)(shi)(shi)(shi)(shi)硬(ying)(ying)(ying)(ying)(ying)度(du)(du)(du)(du)，家(jia)(jia)裝(zhuang)不(bu)銹(xiu)(xiu)鋼管(guan)(guan)(guan)維(wei)(wei)(wei)氏(shi)(shi)(shi)(shi)(shi)硬(ying)(ying)(ying)(ying)(ying)度(du)(du)(du)(du)試(shi)驗(yan)也是(shi)(shi)(shi)一種壓痕試(shi)驗(yan)方法(fa)(fa)(fa)(fa),可(ke)(ke)用于(yu)(yu)測定很薄的(de)(de)(de)金(jin)屬材(cai)(cai)料和表(biao)面層硬(ying)(ying)(ying)(ying)(ying)度(du)(du)(du)(du),它具有布(bu)氏(shi)(shi)(shi)(shi)(shi)、洛(luo)氏(shi)(shi)(shi)(shi)(shi)法(fa)(fa)(fa)(fa)的(de)(de)(de)主要優點(dian),而(er)克(ke)服了(le)它們的(de)(de)(de)基本缺點(dian),但(dan)不(bu)如洛(luo)氏(shi)(shi)(shi)(shi)(shi)法(fa)(fa)(fa)(fa)簡便(bian),維(wei)(wei)(wei)氏(shi)(shi)(shi)(shi)(shi)法(fa)(fa)(fa)(fa)在(zai)鋼管(guan)(guan)(guan)標(biao)準中很少用。
