Customer Success Stories

A competitor's coating was failing the PR2 Annex F testing, so a customer partnered with PST to apply a proven tungsten carbide coating using our proprietary D-Gun application process on their gates and seats.

An open and shut solution

PST replaced a competitor's coating on furnace rolls used to transport steel strip through an annealing furnace in a galvanizing line. Our coating can withstand the extreme temperatures the rolls are exposed to while resisting pickup from various oxides.

Eliminating Pickup: Hearth rolls in AHSS production

We worked with aviation OEMs around the world to migrate special  surface technology processes to locations close to overhaul and component repair shops to reduce downtime.

Less downtime. More sky-time.

Our ExoPro^TM coating replaced hard chrome plating on a mud motor rotor, resulting in an improved life at an economical cost. Our solution provided the necessary protection to resist corrosion and wear, increasing the life from 1-2 runs to 3-4 runs.
