Boron carbide (B4C) coatings are prepared by an RF inductively coupled plasma (ICP) torch with different amounts of hydrogen introduced into the sheath gas. The effects of the added hydrogen on the characteristics of the plasma are diagnosed by optical emission spectroscopy and high speed photography. The effects on the melting of B4C particles in the plasma are studied by scanning el... https://safeersappliancers.shop/product-category/bosch-ksv36aw4pg-serie-6-a-free-standing-fridge-346-litres-white/
