METHOD OF APPLYING COATINGS OF REFRACTORY METALS AND THEIR COMPOUNDS WITH LIQUID NONMETALS Russian patent published in 2000 - IPC

FIELD: metal coatings and corrosion protection. SUBSTANCE: after initial material is properly positioned, charge is blown up at specified distance from surface to be treated. Method is distinguished by that initial material is placed in porous jet shell of jet charge having porosity m ≥ 3, half-opening angle of jet cut 25 ≤ α ≤ 70^o, and load factor r = m ρ_exδ_ex/ρ_shδ_sh, where ρ_ex is explosive density, δ_ex explosive layer thickness, ρ_sh density of jet shell material, and δ_sh jet shell thickness, jet charge being positioned at distance at least 200 mm from surface to be treated. EFFECT: strengthened attachment of light nonmetals to refractory metals. 2 dwg, 6 ex
