Nano-structured CVD tungsten carbide coating protects against wear and corrosion

Drilling tools operate in extremely abrasive, erosive and corrosive environments which reduce tool life, especially in the case of sour well applications. This paper discusses a new family of low temperature Chemical Vapour Deposition (CVD) Tungsten Carbide coatings proven to increase tool life and thus reduce expensive downtime and drilling operation costs particularly in new frontier, harsh and difficult drilling conditions.
