Grip and Wear Applications
Spark-deposited carbide coatings are often used for two high-value outcomes: improving grip and reducing wear. When tools slip, gall, pull slugs, or wear out prematurely, a controlled coating strategy can extend uptime, reduce rework and delay replacement costs.

Where coatings help most
Grip Improvements
- Reduce slipping on clamps, collets and grippers
- Improve feed reliability on contact surfaces
- Enhance traction in high-cycle handling
Wear Protection
- Reduce galling and abrasion in contact zones
- Extend time between sharpenings
- Protect edges, corners and wear faces
Repair and Restore
- Recover worn areas without high-heat distortion
- Restore function on expensive tooling
- Reduce downtime vs replacement
Grip applications
Tube bending, forming and handling
- Tube bending dies
- Clamps and pressure dies
- Collets and gripping jaws
- Pusher pads, feed fingers and handling tooling
A textured coating in the contact zone can reduce slip, improve feed repeatability and help minimize marks caused by “chasing” traction through higher clamp pressure.
Chuck jaws and workholding
- Chuck jaws
- Fixture contact pads
- Custom workholding surfaces
When grip is inconsistent, parts can walk, chatter or shift under load. Targeted grip zones can stabilize workholding without changing the entire fixture.
Wear applications
Punching, stamping, forging and extruding
- Reduce slug pull-back
- Minimize galling and adhesive wear
- Extend time between sharpenings
Die casting
- Restore parting lines
- Protect gates and runners
- Reduce soldering, seizing of cores and heat checking
Wood, paper and perishable tooling
- Saws, cutters, planer blades and chipper knives
- Die cutting knives and shear blades
Maintenance and repair
- Restore tolerances on shafts and wear areas
- Improve service life on high-wear contact points
How to choose the right approach
- Define the wear mode: abrasion, galling, impact or slip
- Target the zone: coat only where performance is needed
- Protect critical fits: control boundaries to keep assemblies predictable
- Prep and QA: repeatable surface condition improves repeatability
