Yam Tseem Ceeb Muaj Feem Xyuam Los Ntawm Kev Hnav Hnav-resistant Sib Tsoo Hlau Pob (1)

Sab nrauv ib puag ncig rau cov khoom hnav: hardness, lub zog, ceev, lub kaum ntse ntse, kub, av noo, particle loj, thiab lwm yam.

1. Abrasive hardness: Ntawm ntau tus yam ntxwv ntawm hnav, qhov cuam tshuam ntawm cov khoom hardness yog qhov tseem ceeb tshaj plaws.

2. Lub zog; ntawm no tshwj xeeb yog hais txog lub siab ntawm cov khoom tiv thaiv abrasive. Raws li kev hnav siab nce, tus nqi hnav nce vim tias qhov tob tob ntawm cov abrasive mus rau qhov hnav-resistant steel pob nce nrog kev nce siab, thiab lub zog ntawm kev txiav deformation ntawm cov khoom nce ntxiv.

3. Mill ceev: Ntau hom hnav muaj qhov sib txawv ntawm qhov hnav ceev. Thaum zawv zawg hnav, cov nyhuv ntawm kev ceev tsis pom tseeb. Tus nqi hnav corrosion muaj qhov tseem ceeb ntawm kev hnav. Thaum qhov cuam tshuam ceev nce mus txog ib theem, cov khoom siv uas tsis hnav nyob rau hauv zawv zawg hnav lossis cov xwm txheej ceev kuj tseem hnav rau lub sijhawm no.
