Your Component |
| Component name |
Make it descriptive |
|
| Function |
Is it rolling, sliding, in static contact, etc. |
|
| Base material |
Low carbon steel, medium carbon steel, alloy steel, al alloy, etc.
|
|
| Fabrication method |
Cast, machined, ground, etc. |
|
| Heat-treatment |
The temperature which you don't want to exceed when surface engineering
|
|
| Environment |
Is it saline, oxidising, caustic etc. |
|
| Lubrication |
Is it oiled or greased |
|
| Operating temperature |
The maximum its likely to see |
|
| Counterface material |
It could be another engineering part or it could be a product |
|
| Counterface hardness |
If it's an engineering part, how hard is it? |
|
| Abrasivity of product |
If the contact is against a product, does it have a hard filler
or abrasive nature. How hard? |
|
| Corrosively of product |
Salt water, acid, etc. |
|
| Mode of degradation |
What is dominant? Wear, corrosion, fatigue, etc. |
|
| Your basic requirement |
Low wear? Low friction? Anti corrosion? etc. |
|
| The load |
The maximum value |
|
| The likely contact area |
Is it over a large area or concentrated? |
|
| The specific load |
Divide the load by the area |
|
| Contact conditions |
Impact, cyclic loading, static loading, or just sliding? |
|
| Hardness |
How hard do you want the surface to be? |
|
| Surface finish |
Your required finished value |
|
| Finishing constraints |
Can you post-finish after surface treatment? What dimensions are
critical? |
|
| Thickness |
How thick do you want the coating or case? It will depend on the
load |
|
| Coverage |
Where must it be coated or treated? Are there any holes or inaccessible
features? |
|
