Rau kev yuav khoom, qhov sib txawv ntawm qib ntawm cov cuab yeej txiav alloy feem ntau cuam tshuam rau tus nqi yuav khoom, kev siv tau zoo, thiab tus nqi tag nrho - ua tau zoo. Kev nkag siab txog qhov sib txawv no ua rau muaj kev sib txuam ntawm cov kev xav tau ntau lawm thiab zam kev yuav khoom pov tseg. Cov kev sib txawv tseem ceeb ntawm cov qib sib txawv ntawm cov cuab yeej tsom rau plaub qhov tseem ceeb: cov khoom siv, kev ua tau zoo, cov xwm txheej siv tau, thiab tus nqi, uas ua raws li cov kev cai tseem ceeb ntawm kev xaiv cov khoom.
Tsawg-kawg hlau txiav cov cuab yeej siv feem ntau siv cov khoom siv hlau tsis muaj txheej tshwj xeeb. Lawv hardness thiab hnav tsis kam yog qhov nruab nrab, ua rau lawv haum rau cov hlau zoo tib yam thiab tej yam yooj yim txiav. Lawv muaj tus nqi qis tab sis lub neej ua haujlwm luv luv, yuav tsum tau hloov ntau zaus, ua rau cov nqi xa khoom mus sij hawm ntev -. Lawv tsim nyog rau me me -batch, qis- cov txheej txheem ua tiav. Cov cuab yeej nruab nrab -cov cuab yeej siv siab- zoo alloy substrates nrog cov txheej txheem yooj yim, muaj qhov sib npaug ntawm hardness thiab toughness. Lawv tau sib xws nrog ntau yam ntaub ntawv xws li stainless hlau thiab txhuas alloys, nrog rau kev pab cuam lub neej 2-3 npaug ntawm qhov qis kawg. Nrog rau tus nqi nruab nrab thiab cov nqi ua tau zoo, lawv yog thawj qhov kev xaiv rau feem ntau cov lag luam 'kev yuav khoom.
High-kawg txiav cov cuab yeej siv ultra- cov hmoov nplej zoo los yog nano{2}} txheej tshuab, uas muaj cov tawv tawv thiab kub ua haujlwm. Lawv tsim nyog rau kev ua haujlwm nyuaj xws li siab - kub alloys thiab cov ntaub ntawv nyuaj thiab nkig, nrog lub neej ua haujlwm ntev thiab kev ua haujlwm siab, uas tuaj yeem txo qhov zaus ntawm cov cuab yeej hloov pauv thiab cov khoom poob. Txawm li cas los xij, lawv cov nqi tsev yog qhov siab, ua rau lawv haum rau huab hwm coj thiab siab - cov txheej txheem ua tiav. Thaum yuav khoom, nws yog ib qho tsim nyog yuav tsum xav txog cov khoom siv thiab cov peev txheej tsim khoom, sib npaug tus nqi ntawm ib lub cuab yeej nrog cov txiaj ntsig siv sijhawm ntev, thiab tsis txhob "siv cov ntaub ntawv qib siab- rau qib qis- kawg lub hom phiaj" lossis "siab noj nrog tsawg- cov ntaub ntawv qib".
