Tribology Results
Wear Test of Maraging Steel (Laser Sintered)
A disc of material was produced to fit the ‘pin on disc’ test unit (aprox 75mm diameter).
A set load was then applied through a pin of pre defined hardness for a given distance at a given speed. Hardness levels taken.
The test disc was then cryogenically treated and the test process repeated.

Wear scar - Pre cryogenic Treatment

Wear scar - Ater Cryogenic Treatment

When comparing the two pictures it is clear that the wear scar is much reduced and that the debris after treatment is a much finer particle.
We measured the size and depth of the scar with an optical profile tool and the following graphs produced:-
