Investigation of how nitrocarburization affects pistons from Epiroc (English)
Abstract [en]

The degree project has been done at the quality department at Epiroc in Fagersta aspart of the continuous quality control work that takes place there. In the project, it hasbeen investigated how a piston in a down-the-hole hammer is affected by the heattreatment process called nitrocarburization which is performed to give the material anincrease in surface hardness. The main part of the project has been to measure theproducts of interest in a measuring machine before and after nitrocarburization andthen analyzing the result. After the measurements had been made it could beobserved that there was an increase in dimension on the locations of the piston beingmeasured.

Abstract [sv]

Arbetet har gjorts på kvalitetsavdelningen på Epiroc i Fagersta som en del i detkontinuerliga kvalitetsarbete som sker där. I arbetet har det undersökts hur kolvar tillsänkborrhammare påverkas av värmebehandlingen nitrokarburering som utförs föratt ge en ökad ythårdhet hos materialet. Huvuddelen i arbetet har varit att mäta uppde berörda produkterna i mätmaskin före respektive efter nitrokarburering ochanalysera resultatet. Efter gjorda mätningar kunde det observeras att det skett enökning i dimension på de delar av kolven som uppmätts.
