(2) Thermal txau

Cov txheej txheem ntawm atomizing molten hlau thiab txau rau saum npoo ntawm lub workpiece los ua ib txheej yog hu ua thermal spraying, xws li thermal spraying ntawm zinc, thermal spraying ntawm txhuas, thiab lwm yam.

(3) Kub stamping

Cov txheej txheem ntawm cov cua sov thiab nias cov ntawv hlau los npog qhov chaw ntawm lub workpiece, ua ib txheej txheej, hu ua kub stamping, xws li kub stamping aluminium ntawv ci.

(4) Kev kho cua sov

Cov txheej txheem nyob rau hauv uas lub workpiece los mus rau hauv kev sib cuag nrog ib tug chemical tshuaj, heats li, thiab txiav txim ib lub caij mus rau lub nto ntawm lub workpiece nyob rau hauv lub kub kub yog hu ua tshuaj kho cua sov, xws li nitriding, carburizing, thiab lwm yam.

(5) Overlay welding

Cov txheej txheem ntawm kev tsim cov txheej txheem vuam los ntawm kev vuam cov hlau tso rau ntawm qhov chaw ua haujlwm yog hu ua overlay welding, xws li overlay welding ntawm hnav-resistant alloys.

Vacuum method

Txoj kev no yog cov txheej txheem ntawm kev txiav txim cov khoom siv gasification los yog ionization rau tso rau ntawm qhov chaw ntawm lub workpiece nyob rau hauv lub siab nqus tsev, tsim ib txheej. Txoj kev tseem ceeb yog.

(1) Lub cev Vapor Deposition (PVD)

Nyob rau hauv lub tshuab nqus tsev, cov txheej txheem ntawm vaporizing hlau rau hauv atoms los yog molecules, los yog hloov nws cov ions rau hauv ions, thiab ncaj qha tso rau ntawm qhov chaw ntawm lub workpiece los tsim ib txheej yog hu ua lub cev vapor deposition. Cov kab hluav taws xob tso tawm los ntawm cov khoom tsis muaj tshuaj lom neeg, xws li evaporation plating, sputtering plating, ion plating, thiab lwm yam.

(2) Ion implantation

Cov txheej txheem ntawm kev txhaj tshuaj sib txawv rau hauv qhov chaw ntawm lub workpiece nyob rau hauv high voltage los hloov nws nto yog hu ua ion implantation, xws li boron txhaj.

(3) Chemical Vapor Deposition (CVD)

Cov txheej txheem ntawm kev tsim cov txheej txheem ntawm cov khoom tso rau ntawm qhov chaw ua haujlwm vim yog cov tshuaj lom neeg ntawm cov tshuaj gaseous nyob rau hauv qis siab (qee zaum kuj ntawm atmospheric siab) hu ua chemical vapor deposition, xws li vapor deposition ntawm silicon oxide, silicon nitride, thiab lwm yam.

Lwm txoj kev

Feem ntau yog mechanical, tshuaj, electrochemical, thiab lub cev txoj kev. Cov txheej txheem tseem ceeb yog:

(1) Painting

Cov txheej txheem ntawm kev siv cov xim (organic los yog inorganic) rau saum npoo ntawm lub workpiece los tsim ib txheej yog hu ua painting, xws li tshuaj tsuag los yog txhuam.

(2) Kev cuam tshuam plating

Cov txheej txheem ntawm kev tsim cov txheej txheem ntawm lub workpiece nto los ntawm cov neeg kho tshuab poob siab yog hu ua cuam tshuam plating, xws li cuam tshuam galvanizing.

(3) Laser nto kho

Cov txheej txheem ntawm irradiating nto ntawm lub workpiece nrog lub laser hloov nws cov qauv hu ua laser nto kho, xws li laser quenching, laser remelting, thiab lwm yam.

(4) Superhard membrane technology

Cov thev naus laus zis ntawm kev npaj cov yeeb yaj kiab superhard nyob rau saum npoo ntawm cov khoom siv lub cev lossis tshuaj lom neeg yog hu ua superhard film technology. Xws li pob zeb diamond films, cubic boron nitride films, thiab lwm yam.

(5) Electrophoresis thiab electrostatic txau

1. Electrophoresis

Lub workpiece yog muab tso rau hauv ib tug electrode nyob rau hauv ib tug conductive dej-soluble los yog dej emulsified txheej, tsim ib tug Circuit Court nrog lwm electrode nyob rau hauv lub txheej. Nyob rau hauv qhov kev txiav txim ntawm ib qho hluav taws xob teb, cov tshuaj txheej tau dissociated rau hauv ions them nqi, nrog cations tsiv mus rau cathode thiab anions tsiv mus rau lub anode. Cov ions raug nqi no, nrog rau cov xim adsorbed, electrophoretic mus rau saum npoo ntawm lub workpiece los tsim ib txheej txheej, hu ua electrophoresis.

2. Electrostatic txau

Cov txheej txheem ntawm kev tau txais cov xim pleev xim los ntawm kev coj cov atomized tsis zoo them cov xim pleev xim rau ntawm qhov chaw ua haujlwm zoo nyob rau hauv qhov kev txiav txim ntawm high voltage direct tam sim no hluav taws xob teb yog hu ua static spraying.
