Cov hlau tuaj yeem muab faib ua cov hlau tsis yog- alloy, qis- alloy, thiab siab- alloy steels, nrog rau txhua hom cuam tshuam cov lus pom zoo tig. Stainless hlau yog categorized rau ferritic / martensitic, austenitic, thiab duplex hom, txhua yam yuav tsum tau tshwj xeeb txoj kev tig. Muaj tsib yam tseem ceeb ntawm cam khwb cia hlau: grey cam khwb cia hlau, ductile hlau, malleable hlau, compacted graphite hlau, thiab austempered ductile hlau. High- kub alloys, yam ntxwv zoo heev mechanical zog thiab creep tsis kam ntawm siab kub, muab faib ua plaub pawg: npib tsib xee-raws li, hlau-raws li, cobalt-raws li, thiab titanium alloys. Cov pab pawg tsis yog{11}}ferrous hlau encompasses mos uas tsis yog{12}}ferrous hlau-xws li txhuas, tooj liab, tooj liab, tooj dag, thiab magnesium{14}}nrog rau hlau-matrix composites. Cubic boron nitride (CBN) cov cuab yeej feem ntau yog siv los tig cov hlau tawv.
Yuav kom ua tau raws li qhov yuav tsum tau ua rau cov arrays ntawm convex cylindrical nto nrog sag loj, ib qho ultra-precision tig txoj kev tuaj yeem ua haujlwm. Tom qab txheeb xyuas cov ntsiab lus tseem ceeb uas cuam tshuam rau pob zeb diamond tig, kev tshawb nrhiav thiab kev tshawb nrhiav binary tau tsim los txiav txim siab txoj kev tig. Txoj kev tshawb nrhiav binary ua tiav tau txheeb xyuas qhov kev hloov pauv thiab CNC program; Tom qab tig qhov kev sim ntawm ib qho ultra-paj lathe precision yielded micro-structured arrays nrog loj sag thiab deg profile yuam kev ntawm 135 nm. Cov txiaj ntsig tau pom tias txoj kev tshawb nrhiav binary raug txiav txim siab tig trajectories thiab siv tau rau ob qho tib si spherical thiab aspherical profiles.
Txhawm rau tshawb xyuas qhov cuam tshuam ntawm kev hloov pauv thiab kev ua haujlwm ntawm lub tshuab ua haujlwm ntawm qhov chaw ua haujlwm zoo thaum lub sijhawm ib zaug -taw tes pob zeb diamond tig ntawm germanium infrared lo ntsiab muag, ultra- precision tig thwmsim tau ua ntawm ib zaug -crystal germanium. Cov kev sim siv ib zaug xwb- cov cuab yeej siv lead ua pob zeb diamond nrog peb qhov sib txawv rake thiab tshuaj xyuas qhov sib txawv xws li qhov tob ntawm kev txiav, pub tus nqi, ntxaiv ceev, thiab kev siv cov kua dej sib txawv.
