Metal Surface Test | Cerma STM-3 Coating Thickness Proof
Metal Surface Test After Cerma STM-3 Treatment
Scientific bore measurement testing demonstrates Cerma STM-3's ability to create a measurable Silicon Carbide (SiC) ceramic coating on metal surfaces. This test provides physical proof of the coating thickness and surface improvement.
Test Results Summary
| Measurement | Value |
|---|---|
| Bore Measure Before Treatment | 2.5612" |
| Bore Measure After Treatment | 2.5620" |
| Difference in Bore Measurement | 0.0008" |
| Coating Thickness | 20.32μm ÷ 2 = 10.16 μm |
What This Test Proves
- Measurable coating – Cerma STM-3 creates a physical ceramic layer on metal
- Precise thickness – 10.16 microns of SiC coating applied
- Smooth surface – Treatment achieves improved surface finish
- Self-limiting – Once cured, no additional coats can be applied to the sealed surface
Key Finding
"Cerma, once cured, will not allow any additional coats to be laid down on the now sealed surface."
This demonstrates that Cerma STM-3 creates a permanent, one-time coating that fully seals and protects metal surfaces. The treatment doesn't continue to build up – it reaches optimal thickness and stops.
Understanding the Coating
| Characteristic | Benefit |
|---|---|
| 10.16 μm thickness | Optimal protection without affecting tolerances |
| Silicon Carbide (SiC) composition | 9.5 Mohs hardness – extremely wear resistant |
| Self-limiting application | Won't over-coat or build up excessively |
| Smooth surface finish | Reduced friction and improved efficiency |
Why This Matters
This metal surface test provides scientific evidence that Cerma STM-3:
- Actually creates a physical coating (not just a lubricant film)
- Delivers consistent, measurable thickness
- Produces a permanent ceramic seal
- Improves surface smoothness for reduced friction
