Kev tsom xam Atomic Force Microscopy (AFM) tuaj yeem txheeb xyuas qhov cuam tshuam ntawm kev co kev ntxhov siab - kev kho mob ntawm hardness ntawm LR / D steel raws li hauv qab no:

Surface Topography thiab Roughness Analysis

 

Kev soj ntsuam Topography: AFM tuaj yeem siv tau kom tau txais nanoscale topography cov duab ntawm qhov chaw ntawm LR / D steel. Kev vibration kev ntxhov siab - kev kho mob yuav ua rau muaj kev hloov pauv hauv cov qauv microscopic ntawm cov hlau nto, xws li kev txav mus los thiab kev ua kom zoo ntawm cov nplej. Cov kev hloov no yuav tshwm sim hauv qhov chaw saum toj kawg nkaus. Yog hais tias lub nto ua smoother thiab cov nplej yog finer thiab ntau uniform tom qab kev kho mob, nws qhia tau hais tias kev vibration kev nyuaj siab - kev kho mob pab tau txhawb lub optimization ntawm microscopic qauv thiab tej zaum yuav ua rau kom lub hardness.

 

Roughness Quantification: Nto roughness tsis, xws li hauv paus - txhais tau tias - square roughness (Rq) thiab qhov nruab nrab roughness (Ra), tuaj yeem ntsuas los ntawm AFM. Feem ntau hais lus, muaj qee qhov kev sib raug zoo ntawm qhov chaw roughness thiab hardness. Ib tug smoother nto muaj ib tug kuj zoo sib xws kev nyuaj siab tis thaum raug rau sab nraud quab yuam, uas yog zoo rau nce cov khoom hardness. Yog hais tias qhov saum npoo roughness txo qis tom qab kev vibration kev ntxhov siab - kev kho mob, nws qhia tau hais tias qhov zoo ntawm qhov saum npoo tau txhim kho thiab qhov hardness yuav nce ntxiv.

Dislocation thiab Defect Analysis

 

Dislocation Observation: AFM tuaj yeem soj ntsuam cov qauv dislocation ntawm cov khoom nto rau qee qhov. Thaum lub sij hawm vibration kev nyuaj siab - txoj kev kho mob nyem, dislocations yuav txav thiab ntau, thiab dislocation ceev yuav hloov tom qab kho. Yog hais tias lub dislocation ceev nce thiab kev sib cuam tshuam ntawm dislocations yog txhim khu kev qha, nws yuav cuam tshuam qhov ntxiv txav ntawm dislocations thiab ua rau kom cov deformation tsis kam ntawm cov khoom, yog li nce lub hardness. Kev cuam tshuam ntawm kev faib tawm thiab kev hloov ceev ntawm hardness tuaj yeem txheeb xyuas los ntawm kev txheeb xyuas AFM cov duab.

 

Defect Detection: Txheeb xyuas qhov tsis xws luag ntawm cov khoom nto, xws li qhov thiab cov kab nrib pleb. Kev vibration kev nyuaj siab - kev kho mob yuav pab tau

kho los yog txo qee qhov tsis xws luag thiab txhim kho cov txheej txheem kev ncaj ncees ntawm cov khoom, yog li muaj kev cuam tshuam zoo rau hardness. Los ntawm kev sib piv cov teeb meem tsis xws luag ua ntej thiab tom qab kev kho mob, qhov kev pab cuam rau hardness tuaj yeem soj ntsuam.
