To understand the anisotropy dependence of the damage evolution and material removal during the machining process of MgF _2 single crystals. nanoscratch tests of MgF _2 single crystals with different crystal planes and directions were systematically performed. and surface morphologies of the scratched grooves under different conditions were analyzed. The experimental results indicated... https://www.cubiertasytubulares.com/product-category/make-up/
