Ntxiv Ib Cov Kabmob Cov Kabmob Ntawm Cov Txheej Txheej Txheej thiab Tuag

Ntxiv ib txheej txheej ntawm cov txheej tawv tawv thiab cov tuag

▲ Daim duab 5 Cov pob txha hardness gradient nkhaus ntawm cov txheej tawv tawv tso tom qab nitriding ntawm cov pwm

Lub hardness ntawm cov tuag tom qab kev kho cua sovHv 2000, thiab lub thickness yog feem ntau<5μm. The surface of heavy-duty die is coated with a thin, hard hard coating, which is easy to collapse and collapse under heavy load. Therefore, it is required to nitride on the surface of the mold before depositing hard coating, hoping that the hardness of the surface will be reduced slowly.

FIG. 5 qhia tau hais tias cov pob txha hardness gradient nkhaus ntawm cov txheej tawv tawv tso tom qab nitriding ntawm cov tuag. Vertical axis yog hardness thiab kab rov tav axis yog qhov tob. Daim duab sab laug yog qhov hardness gradient nkhaus ntawm cov txheej nitriding. Daim duab nyob rau hauv nruab nrab yog ib tug hardness gradient nkhaus rau lub deposition ntawm TiN nkaus xwb. Daim duab ntawm sab xis qhia tau hais tias cov pob txha hardness gradient nkhaus ntawm cov txheej txheej nyuaj tso tom qab qhov kub tsis tshua muaj nitriding ntawm qhov tuag. Nws tuaj yeem pom tau tias qhov hardness gradient txo qis, uas yog qhov tsim nyog rau kev ua haujlwm hnyav.
