Surface structuring of case hardened chain pins by cold-sprayed microparticles to modify friction and wear properties

- Microscale titania particles were bonded to case hardened steel pins using cold spraying.
- CFD simulation was used to get a better understanding of the process.
- Hardness of the structured chain pins was not decreased during cold spraying.
- Friction coefficient of the structured chain pins decreased significantly.
- Surface structure and chemistry of the particle structured pins were characterized.
