Codsiga tijaabada adag

Tijaabiyaha adkaanta waa qalab lagu cabbiro adkaanta walxaha. Sida laga soo xigtay walxaha kala duwan ee la cabbirayo, tijaabiyaha adkaanta waxaa loo isticmaali karaa meelo kala duwan. Tijaabiyeyaasha adkaanta qaarkood waxaa loo isticmaalaa warshadaha farsamaynta farsamada, waxayna inta badan cabbiraan adkaanta walxaha birta. Sida: Tijaabiyaha adkaanta Brinell, Tijaabiyaha adkaanta Rockwell, Tijaabiyaha adkaanta Leeb, Tijaabiyaha adkaanta Vickers, Tijaabiyaha microhardness, Tijaabiyaha adkaanta Shore, Tijaabiyaha adkaanta Webster iwm. Baaxadaha codsiga gaarka ah ee tijaabiyayaashan adkaanta waa sida soo socota:

Tijaabiyaha adagaanta Brinell:inta badan waxaa loo isticmaalaa tijaabinta adkaanta ee birta la been abuuray iyo birta la shubay oo leh qaab-dhismeed aan sinnayn. Adkaysiga Brinell ee birta la been abuuray iyo birta la shubay ee cawlan waxay leedahay isku-xidhnaan wanaagsan oo la leh tijaabada jiidista. Tijaabada adkaanta Brinell waxaa sidoo kale loo isticmaali karaa biraha aan birta ahayn iyo birta jilicsan. Dhexroorka kubbadda dhexroorka yar wuxuu cabbiri karaa walxaha cabbirka yar iyo kuwa khafiifka ah, wuxuuna cabbiri karaa dukaamada daaweynta kulaylka iyo waaxaha kormeerka warshadaha ee warshadaha mishiinada kala duwan. Tijaabada adkaanta Brinell waxaa inta badan loo isticmaalaa kormeerka alaabta ceeriin iyo alaabada nus-dhammaystiran. Sababtoo ah gelinta weyn, guud ahaan looma isticmaalo kormeerka alaabta la dhammeeyay.

 

Tijaabiyaha adag ee Rockwell:Tijaabi biraha kala duwan ee ferrous iyo kuwa aan ferrous ahayn, tijaabi adkaanta birta la damiyay, birta la damiyay iyo kuwa la hagaajiyay, birta la damiyay, birta la qallajiyey, saxannada dhumucdoodu kala duwan tahay, walxaha carbide-ka, walxaha birta budada ah, dahaarka buufinta kulaylka, shubka qaboojiyey, shubka la been abuuri karo, birta aluminium-ka ah, birta la sido, saxannada birta khafiifka ah ee la qallajiyey, iwm.

Tijaabiyaha Adkaanshaha Rockwell ee Dabiiciga ah:Waxaa loo isticmaalaa in lagu tijaabiyo adkaanta birta xaashida khafiifka ah, tuubooyinka derbiga khafiifka ah, birta qaloocan ee kiiska adag iyo qaybo yaryar, dahaarka adag, carbide, birta qaloocan ee kiiska adag, xaashida adag, birta qaloocan ee la damiyay oo la hagaajiyay, birta la qaboojiyey ee la shubay, birta la shubay, aluminium, naxaas, magnesium iyo biraha kale ee dahaarka ah.

 

Tijaabiyaha adag ee Vickers: cabbir qaybo yaryar, saxanno bir ah oo khafiif ah, bir bir ah, xaashiyaha IC, fiilooyinka, lakabyo adag oo khafiif ah, lakabyo elektaroonik ah, galaas, dahabka iyo dhoobada, biraha ferrous, biraha aan ferrous ahayn, xaashiyaha IC, dahaarka dusha sare, biraha la dahaadhay; galaas, dhoobada, agate, dhagaxyada dhagaxa ah, iwm.; tijaabada qoto dheer iyo heerka qallafsanaanta lakabyada kaarboonaysan iyo deminta lakabyada adag. Habaynta qalabka, warshadaha elektaroonigga ah, qalabka caaryada, warshadaha saacadaha.

 

Knooptijaabiyaha adag:si ballaaran ayaa loo isticmaalaa in lagu cabbiro adkaanta yar ee muunadaha yaryar iyo kuwa khafiifka ah, dahaarka gelinta dusha sare iyo muunadaha kale, iyo in lagu cabbiro adkaanta Knoop ee walxaha jilicsan iyo kuwa adag sida galaaska, dhoobada, agate, dhagaxyada macmalka ah, iwm., baaxadda khuseysa: daaweynta kulaylka, kaarburization, lakabka adkaynta deminta, dahaarka dusha sare, birta, biraha aan birta ahayn iyo qaybaha yaryar iyo kuwa khafiifka ah, iwm.

 

Tijaabiyaha adag ee Leeb:birta birta ah iyo tan la shubay, birta qalabka birta ah, birta cawlan ee la shubay, birta dushiisa, aluminiumka la shubay, birta naxaasta ah ee naxaasta ah (naxaas), birta naxaasta ah ee naxaasta ah (naxaas), naxaasta saafiga ah, birta la shubay, birta kaarboon, birta chrome, birta chrome-vanadium, birta chrome-nickel, birta chrome-molybdenum, birta chrome-manganese-silicon, birta aadka u xoog badan, birta aan daxalka lahayn, iwm.

 

Shmacdantijaabiyaha adag:Waxaa inta badan loo isticmaalaa in lagu cabbiro adkaanta balaastikada jilicsan iyo caagga adag ee caadiga ah, sida caag jilicsan, caag macmal ah, duubayaasha caagga daabacaadda, qalabka thermoplastic elastomers, maqaar, iwm. Waxaa si weyn loogu isticmaalaa warshadaha balaastikada, warshadaha caagga iyo warshadaha kale ee kiimikada, oo ay ku jiraan adkaanta balaastikada adag iyo caagga adag, sida resins-ka adag ee thermoplastic, agabka dabaqa, kubbadaha bowling-ka, iwm. Waxay si gaar ah ugu habboon tahay cabbirka adkaanta goobta ee alaabada caagga iyo balaastikada la dhammeeyay.
