Onye nyocha Calo, nke a makwaara dị ka onye na-agba bọọlụ ma ọ bụ onye nyocha ọkpụrụkpụ, bụ ngwá ọrụ dị mfe ma dị ọnụ ala nke a na-eji atụ ọkpụrụkpụ nke mkpuchi. A na-eji mkpuchi nwere ọkpụrụkpụ dị n'agbata 0.1 na 50 micrometers, dị ka mkpuchi Physical Vapor Deposition (PVD) ma ọ bụ mkpuchi Chemical Vapor Deposition (CVD), eme ihe n'ọtụtụ ụlọ ọrụ iji melite ihe onwunwe nke ngwaọrụ na ihe ndị mejupụtara ya. A na-ejikwa onye nyocha Calo tụọ ọnụ ọgụgụ nke mkpuchi mkpuchi mgbe ule mkpuchi nke ejiji Pin-on-Disc Tester mee.
Ihe nleba anya Calo nwere ihe njide maka elu ka a nwalere ya na nchara nchara nke dayameta ama ama nke na-atụgharị megide elu site na ogwe na-atụgharị na moto ebe a na-etinye ihe ntanye diamond na mpaghara kọntaktị. A na-atụgharị akụkụ ahụ maka obere oge (ihe na-erughị 20 sekọnd maka ọkpụrụkpụ 0.1 ruo 5 micrometer) mana n'ihi ọdịdị abrasive nke tapawa diamond, nke a bụ oge zuru oke iji yi akwa akwa site na mkpuchi dị nro.
