Cov nyhuv ntawm Electroplating Alloy ntawm As-cam khwb cia khoom ntawm hluav taws xob cua sov raj
Tuam Tshoj muaj ntau boron reserves, tus nqi qis, thiab stability. Boron hauv - Fe thiab - Lub solubility ntawm Fe yog tsawg dua 0.0004wt feem pua thiab 0.02wt feem pua. Tom qab ntxiv boron rau hauv Fe-C alloy, feem ntau boron yuav tsim boron carbide los yog precipitate nyob rau hauv daim ntawv ntawm boride nrog siab hardness thiab zoo high-temperature stability thaum lub sij hawm solidification. Kev nce hauv cov ntsiab lus boron tuaj yeem txo qhov austenite cheeb tsam. Thaum cov ntsiab lus boron nce mus rau ib qho nqi, thaj tsam austenite shrinks mus rau ib qho twg, thiab tej zaum yuav tsis muaj kev hloov pauv ntawm lub melting point, uas tsis tuaj yeem ntxiv dag zog los ntawm kev kho cua sov. Qhov twg boron carbide thiab boride theem muaj qhov hnyav hnyav kuj yog nyob ntawm kev txhawb nqa thiab qhwv cov nyhuv ntawm matrix, uas yog, cov matrix xav tau qee qhov hardness thiab ntim feem pua. Nyob rau hauv kev cuam tshuam abrasive hnav, tom qab lub matrix nrog tsawg hardness raug tshem tawm, lub boron carbide los yog boride theem protrudes tawm ntawm hnav nto. Nyob rau hauv qhov rov qab extrusion thiab cuam tshuam ntawm cov khoom abrasive, qhov nyuaj thiab nkig boron carbide thiab boride tuaj yeem tawg, ua rau poob qis ntawm cov khoom siv tiv thaiv kev ua haujlwm ntawm cov hlau. Tsis tas li ntawd, yog tias qhov ntim feem pua cov ntsiab lus ntawm matrix tsawg dhau, nws yuav tsis muaj qhov cuam tshuam zoo ntawm cov theem nyuaj. Hauv kev cuam tshuam abrasive hnav, lub sijhawm nyuaj yuav poob rau hauv cov khoom loj, uas tseem yuav ua rau txo qis ntawm cov hlau abrasive tsis kam. Yog li ntawd, thiaj li yuav ua tau zoo heev hnav tsis kam nyob rau hauv cam khwb cia Fe-CB alloys, lub matrix yuav tsum muaj ib tug tej yam carbon cov ntsiab lus thiab ntim feem pua. Cov kev tshawb fawb uas twb muaj lawm feem ntau tsom rau nruab nrab thiab qis carbon steel, nrog rau me me ntawm cov ntsiab lus carbon ntxiv. Txhawm rau txhawm rau tshawb xyuas ntxiv cov txiaj ntsig ntawm B ntawm cov qauv khov kho thiab cov khoom ntawm Fe-CB alloy ntawm cov ntsiab lus siab carbon, tsab xov xwm no npaj siab xaiv cov ntsiab lus carbon ntawm kwv yees li 1.0wt feem pua rau kev tshawb fawb ua ntej.
