Making Case Hardened Gears - Heat Treatment Oversimplified

G'day everyone,

In this video I will be case hardening a gear. gears are a good candidate to be case hardened, due to the large amount of wear that will be encountered by the gear teeth meshing. I will case harden the outside of the gear in order to harden it and increase the life of the gear. I will also be experimenting with a piece of EN36A case hardening steel, which has higher tensile strength and hardenability than normal low carbon steel. I will also briefly touch ion hardness and hardenability in heat treatment and do a test using some 1045 and A2 air hardening steel. I hope you enjoy the video.
