Stop Hardfacing Delamination: Why Metallurgical Bonding Matters for PDC Bits

It looked perfect in the warehouse. So why did it fail in the well?

How to Spot Quality Before It Fails Downhole.

This is a frustration shared by many drilling engineers: You purchase a PDC bit that looks robust on the surface. But after just a few hundred feet, it comes out with the hardfacing layer suffering from severe delamination, leaving the steel body exposed.

This often forces teams to spend unnecessary time and money on PDC bit repair, or worse, fishing for lost junk in the hole.

At PDC Drill Solution, we engineer our bits to prevent these failures.

1. The Invisible Enemy: “Cold Laps” vs. True Bonding

The most common cause of hardfacing delamination is a lack of a true metallurgical bond.

Cheap Process: Some manufacturers treat hardfacing like a simple “sticker.” The molten carbide sits on top of the steel body without penetrating it. Under downhole vibration, this layer shakes loose.

The PDC Drill Solution Standard: Our process ensures the tungsten carbide matrix fuses with the steel substrate on a molecular level. This strong metallurgical bond ensures the layer won’t shake loose under vibration.

 

2. Cutter Pocket Protection

If you zoom in on our bits, you will see how the hardfacing wraps snugly around the base of each PDC cutter (as shown in the first image).

Why it matters: This is the critical stress zone. Weak protection here leads to erosion and lost cutters.

Our Quality: We provide superior wear resistance by ensuring a dense, non-porous application that protects the cutter pockets from fluid wash.

 

3. Uniformity and Edge Control

Run your hand over the transition zones. If the edges are jagged, it suggests poor craftsmanship. Our skilled technicians ensure the “gold standard” finish you see in our products, guaranteeing consistent performance.

 

Don’t gamble your rig time on bits that only look tough. When you choose PDC Drill Solution, you aren’t just buying a tool; you are buying the assurance that your bit will stay intact, mile after mile.
