Yuav ua li cas nrog dragging hauv lub tshuab nqus tsev nyiaj plating

Thaum lub sij hawm cov txheej txheem yas electroplating, electroplating nto ntawm pwm kab noj hniav zoo li ci heev, tab sis kuj tseem yuav muaj teeb meem ntawm kev rub tawm ntawm pob tshab txhaj tshuaj molding qhov chaw, uas ua rau ntau tus neeg xav tsis thoob. Qhov tseeb, ci pwm plating tsis tas yuav du, thiab kev sib txhuam ntawm nws thiab kub txhaj molded qhov chaw yog qhov loj heev. Feem ntau, kev tsim cov khoom pob tshab tsis raug tso cai rau txau cov pwm tso tawm tus neeg sawv cev, yog li qhov kub txhaj tshuaj zoo li nws tau daig rau pwm, thiab qhov ntev ntawm pwm tsim, qhov kev xav no hnyav dua. Vim tias cov roj stains nyob rau hauv cov hlau saum npoo ntawm cov pwm thaum lub sij hawm cov txheej txheem yas electroplating yuav dhau los ua tsawg thiab tsawg, thiab cov kua nplaum stains sab laug los ntawm kev txhaj tshuaj molded qhov chaw yuav dhau los ua ntau dua, yog li kev sib txhuam quab yuam yuav loj dua thiab loj dua, thiab qhov teeb meem dragging yuav tshwm sim. . Yog hais tias cov pwm ejection nqes hav tsis txaus, nws yuav ua rau luag ntawm cov tshuaj molded qhov chaw.

Txhawm rau txo qhov kev sib txhuam ntawm qhov kev txhaj tshuaj thiab pwm, qhov tseeb, peb tsuas yog yuav tsum siv cov pob zeb diamond muab tshuaj txhuam rau polishing pwm los so cov pwm rub txoj haujlwm, uas tuaj yeem tsis tsuas yog tshem tawm cov kua nplaum ntawm cov pwm plating, tab sis kuj ua rau me me ntawm cov roj stains rau hauv cov hlau. Sab hauv, cov pwm saum npoo yuav du dua, thiab cov teeb meem rub feem ntau tuaj yeem daws tau. Ntau tus kws tshaj lij nyob rau theem nrab thiab theem pib feem ntau ntshai ua qhov no vim tias lawv txhawj xeeb tias cov pwm yuav messed. Qhov tseeb, tsuas yog yuav tsum tau xyuam xim siv paj rwb dipped nyob rau hauv pob zeb diamond muab tshuaj txhuam los txhuam cov pwm thaum lub sij hawm ua cov yas electroplating, tsis txhob siv daim ntaub so, koj tuaj yeem tsis txhob rub cov pwm.

Lub tshuab nqus tsev nyiaj-plating plasma diffusion txheej khoom siv thiab thev naus laus zis

Plasma diffusion infiltration txheej cov cuab yeej thiab thev naus laus zis rau kev ua cov tshuab nqus plating; ion nitriding: N, C thiab lwm cov ntsiab lus tuaj yeem nkag mus rau hauv qhov chaw thiab cov pwm nyob rau hauv cov kab mob paug, txhim kho qhov tawv tawv, qaug zog thiab lwm yam khoom thiab corrosion kuj piv nrog rau tag nrho cov nitriding lub sij hawm kho, cov av noo yog tsawg, deformation yog. me me, thiab cov khoom nto yog tswj tau. Nws tuaj yeem siv rau ntau yam hlau thiab titanium alloy qhov chaw, ntau yam pwm thiab ntau yam khoom siv stainless hlau. Plasma chemical vapor deposition cov cuab yeej thiab thev naus laus zis (ion nitriding, nitrocarburizing) Plasma chemical vapor deposition (PCVD) yog hom tshiab ntawm pulsed DC plasma assisted deposition ntawm cov txheej txheem nyuaj. Nyob rau hauv lub tshuab nqus tsev vacuum nrog ib tug tej yam siab thiab kub, txawv gases nyob rau hauv tsim nyog proportions yog ntxiv, thiab nyob rau hauv qhov kev txiav txim ntawm pulse voltage, uniform plasma yog generated los ntawm glow paug. Raws li cov txheej txheem sib txawv, ntau cov yeeb yaj kiab nyuaj xws li TiN, TiC, TiCN, (Ti, Si)N, (Ti, Si) CN thiab cov txheej txheem ntau cov yeeb yaj kiab tuaj yeem tsim rau ntawm qhov chaw ua haujlwm yuav tsum ua tiav, microhardness mus txog HV2000 --2500. Piv nrog CVD thiab PVD, PCVD thev naus laus zis tuaj yeem paub txog ion nitriding, carburizing thiab txheej hauv tib lub cub tawg ua ntu zus, thiab paub txog cov txheej txheem infiltration composite nrog kev ua haujlwm siab. Cov cuab yeej tsim nyog rau qhov chaw thiab cov cuab yeej uas yuav tsum tau txhim kho qhov hnav tsis kam, corrosion kuj, kub oxidation tsis kam thiab qaug zog. Cov ntaub ntawv ua tiav feem ntau suav nrog: high-speed steel, kub thiab txias steel, txias thiab kub tuag steel, structural steel, stainless hlau, titanium alloy, cemented carbide, thiab lwm yam.
