Nyob rau hauv cov seem twg rail spalling/scraping mas tshwm sim?
Nws feem ntau tshwm sim ntawm me me - vojvoog nkhaus, hnyav- cov kab thauj khoom, ntu nres, qhov chaw tig tawm, thiab qhov chaw uas muaj lub log siab - kev tsheb ciav hlau kev ntxhov siab. Nyob rau hauv cov seem no, rov qab log-rail compression thiab slippage yooj yim ua rau deg qaug zog tawg.
Dab tsi yog qhov laj thawj tseem ceeb ntawm spalling/scraping?
