In order to improve wear resistance and anti-balling of the drill bit during shale oil and gas drilling， Fe₄₈Cr₁₅Mo₁₄C₁₅B₆Y₂ amorphous alloy coatings were prepared on 35CrMo steel substrates by cold spraying （CS） and high velocity air fuel （HVAF） spraying with the hydrophobic surface of coatings made by UV laser. The microstructure and mechanical properties of the coatings were analyzed by scanning electron microscopy （SEM）， X-ray energy spectrometer （EDS） and X-ray diffractometer （XRD）， a contact angle meter was used to characterize the wettability of the coating， and the wetting mechanism was analyzed. The results showed that the Fe-based amorphous alloy coating prepared by CS technology had a denser microstructure and better thermal stability with the amorphous mass fraction up to 90%. The melt in the laser process rapidly cooled on the surface of the coating to form nano-sized condensation and agglomerates to form a micro-nano composite structure. With 7 laser scans， the CS coating had the highest water contact angle on the surface， which represented good hydrophobicity.
