Sezvinhu zvikuru, mabhuroko eenjini nemabhuroko emasilinda einjini zvinofanira kumira tembiricha yakakwira nekumanikidzwa, kuve nechokwadi chekuvharwa kwakavimbika, uye kupa kuenderana kwakanaka kwekubatanidza. Zviratidzo zvavo zvehunyanzvi, zvinosanganisira kuyedza kuomarara uye kuyedza mativi ekururama, zvese zvinoda kudzorwa kwakasimba uchishandisa michina chaiyo. Kuyedzwa kwekuomarara kwemabhuroko nemabhuroko emasilinda kunonyanya kushandiswa kuongorora hunhu hwemakanika hwezvinhu, kuve nechokwadi chekuti zvinosangana nezvinodiwa zvekugadzira.
Zviyedzo zveRockwell hardness zvakakodzera kuongorora kuomarara kwenzvimbo hombe, dzakati sandara dzakadai sema cylinder block planes (semuenzaniso, ma cylinder head mating surfaces, cylinder block bottoms) uye crankshaft hole end faces. Kuti uongorore mhando yepamhepo mumitsetse yekugadzira, zvinodiwa zvekuyedza zvakagadzirwa zvinogona kupihwa. Zviyedzo zveRockwell hardness zvinongoerekana zvaitwa otomatiki zvinogona kubatanidzwa nemutsetse wekugadzira kuti zvibudirire, zvine mashandiro akanaka uye mhedzisiro yakagadzikana. Iyi nzira yekuedza ndiyo inonyanya kushandiswa mukugadzira zvinhu zvemotokari uye inoenderana neISO 6508 neASTM E18 standards.
Zviyedzo zveBrinell hardness zvinoshandiswa pakuongorora kuomarara kwemavara ecylinder block nezvikamu zvine madziro akakora (semuenzaniso, mativi ecylinder block), uye zvinonyanya kukodzera pakuongorora kunaka kwekukanda uye kushanda kwekupisa kwemavara ecylinder esimbi. Zvinofanira kucherechedzwa kuti kuyedza Brinell kunosiya maburi makuru, saka kunofanira kudzivirirwa pazvikamu zvinokurumidza kukuvara zvakaita semadziro ecylinder madziro nepamusoro pemachina chaiwo.
Zviyedzo zvekusimbisa hunyoro zveVickers zvakakodzera pakuyedza hunyoro hwezvikamu zvakatetepa zvemabhuroko esimbi ealuminium alloy, nzvimbo dzemukati dzecylinder liner (kudzivirira kukuvadza nzvimbo dzinovhara), pamwe nekuyedza hunyoro hwemabhuroko nependi dzakagadziriswa nekupisa (semuenzaniso, mabhuroko ane nitride, mabhuroko akadzima) panzvimbo dzemabhuroko esimbi. Nzira iyi yekuyedza inosangana nezvinodiwa zvekuyedza nemazvo zvemainjini emuchadenga neemotokari dzemhando yepamusoro, uye inoenderana neISO 6507 neASTM E92 standards.
Zvichienderana nemabhuroko emasilinda nemisoro yemasirinda yakagadzirwa nezvinhu zvakasiyana, zviyero zvekuomarara zvinotevera zvinogona kutaurwa:
| Chikamu | Zvinhu Zvakajairika | Rudzi rweKuoma Kwekuoma (HB/HV/HRC) | Chinangwa Chekuedza Kwakakosha |
| Kandai Simbi Sirinda Chivharo | HT250/HT300 (Simbi Yakakandwa Yegrey), Simbi yeGraphite Yakatsetseka | 180-240HB20-28HRC | Iva nechokwadi chekuti hazvipfeki uye hazvigadzirisike |
| Aruminiyamu chiwanikwa Cylinder Block | A356+T6, AlSi11Cu2Mg | 85-130 HB90-140 HV 15-25 HRC | Simba rakaringana uye kugona kushanda zvakanaka |
| Kandai Simbi Cylinder Musoro | HT200/HT250, Simbi yeDuctile | 170-220 HB18-26 HRC | Ramba uchitsungirira kupisa kwakanyanya uye iva nechokwadi chekuti nzvimbo yacho yakasimba |
| Aruminiyamu chiwanikwa sirinda musoro | A356+T7, AlSi12Cu1Mg1Ni | 75-110 HB80-120 HV 12-20 HRC | Kuenzanisa zvinhu zvakareruka, kupisa uye simba rechimiro |
Zvichienderana nezvinodiwa zvakasiyana-siyana zvekuedza zvemabhuroko emasilinda einjini, Laizhou Laihua inogona kupa mhinduro dzakagadzirwa zvichienderana nezvigadzirwa zvakasiyana. Izvi zvinosanganisira mamodheru akajairwa, mamodheru akagadziriswa emhando dzese dzeRockwell, Brinell, uye Vickers hardness testers, pamwe nekugadzirwa kwezvishandiso zvakasarudzika zvakagadzirirwa zvigadzirwa—zvese zvine chinangwa chekusimudzira mashandiro ekuedza uye kururama kwekuyera.
