2, Terminology hais txog cov npe thiab cov yam ntxwv ntawm ntau yam hlau / ceramic hmoov

Hmoov

Nws feem ntau yog hais txog qhov sib xyaw ntawm cov khoom sib cais nrog qhov loj ntawm 0.1um ~ 1mm.

Slurry

Cov khoom pub dawb

Plasticized hmoov siv los ua raw khoom rau kev txhaj tshuaj molding lossis hmoov extrusion.

Atomized hmoov

Ib tug hmoov ntawm molten hlau los yog alloy dispersed rau hauv tee dej thiab solidified rau hauv ib tug hais.

(Qhov nruab nrab dispersion feem ntau yog huab cua ceev lossis kua ntws)

Carbonyl hmoov

Hmoov npaj los ntawm thermal dissociation ntawm hlau carbonyl compounds.

Electrolytic hmoov

Hmoov tau los ntawm electrodeposition.

Txo cov hmoov

Hmoov ua los ntawm kev txo cov hlau sib txuas los ntawm kev txo cov tshuaj lom neeg.

Daim txhuam cev hmoov

Cov porous txo cov hmoov yog tsim los ntawm crushing lub siab ntxeem tau hlau daim txhuam cev tau los ntawm txoj kev txo.

Alloy hmoov

Cov hmoov hlau npaj los ntawm ib nrab lossis ua tiav alloying ntawm ob lossis ntau qhov sib xyaw.

Pre-alloyed hmoov

Nws feem ntau yog hais txog tag nrho cov hmoov txhuas ua los ntawm atomizing cov yaj.

Composite hmoov

Txhua qhov yog cov hmoov uas muaj ob lossis ntau qhov sib txawv.

Coated hmoov

Cov hmoov sib xyaw ua ke tsim los ntawm txheej txheej ntawm cov khoom sib txawv ntawm cov khoom sib txawv.

Blended hmoov

Cov hmoov ua los ntawm kev sib tov sib txawv batch ntawm hmoov nrog tib nominal muaj pes tsawg leeg.

Binder

Cov tshuaj ntxiv rau cov hmoov txhawm rau txhim kho lub zog ntawm cov compacts lossis tiv thaiv cov hmoov sib cais uas tuaj yeem raug tshem tawm ua ntej lossis thaum lub sijhawm sintering.

Dopant

Ib qho me me ntawm cov khoom ntxiv rau hauv cov hmoov hlau los tiv thaiv lossis tswj cov recrystallization lossis grain loj hlob ntawm lub cev sintered thaum sintering lossis siv.
