ExpaniteHard-Ti is a solid solution diffusion-based hardening process. No titanium nitrides are formed i.e. no coating is present and no ‘golden colour.
Surface hardness is governed by compressive stresses and typically, a surface hardness of 1000HV+/-100HV is reached. Case depths are typically in the range of 10 to 40µm.
Titanium is known for its light weight,high-strength and very good corrosion resistance. However, in some areas titanium is often coming short; due to its softness the material suffers from poor wear and galling resistance. This is limiting the use of titanium and forcing design engineers to make compromises. Expanite is changing the game by introducing ExpaniteHard-Ti.
Benefits & characteristics after ExpaniteHard-Ti
- Surface hardness increased approx. 5 times over untreated material which gives unprecedented wear resistance!
- No affect on corrosion resistance
- No coating, no titanium nitrides, no spalling risk and no ‘golden colour’
- Possible to post-polish to mirror finish
