Chrome plating used to be the most commonly used coating for these components. The longevity of these tools is vital for improving productivity and reduce drilling cost. The drilling action is no longer effective and the entire assembly needs to be taken out to replace the worn out parts.
After certain period of operation the sealing surface of the tools wear out thereby increasing the clearance and reducing the operational efficiency. These tools are subjected to heavy sliding wear and corrosion due to presence of abrasive slurry particles in the media. Down hole tools are an assembly of oilfield equipment that are used during well drilling and helps the oil well in optimizing the production levels and maintain continuous flow from a reservoir.
