In Reply to: properties and unit for glass coating posted by Vera Prisna on October 13, 2003 at 19:58:41:
: Hi!
: A research project I am working on requires me to match the following properties of glass coating of steel to well definied properties and units in material science/engineering.
: Those properties are:
: (1) hardness
: (2) smoothness
: (3) resistance to abrasion
: (4) Non-sticking properties of surface
: (5) friction of water over steel
: Could anyone point me to online resources that would help me match those 'layman' properties with standard scientific properties used in surface engineering?
: Or even better - could someone just tell me what physical/engineering properties or units I should look for in each of the 5 categories?
: I spoke with a couple of material science experts and they did not really know if there are any formal properties/units describing (2)'smoothness', (4) non-sticking properties of surface, and (5) friction of water over steel.
: If there is a more appropriate message board to post my question, I would love to know about it as well.
: Thank you!
: Best,

Hi Vera
1. See http://www.gordonengland.co.uk/hardness/
2. Surface roughness - Definition:
The measurement of the vertical relief and small-scale irregularities of the terrain surface. See http://www.mfg.mtu.edu/cyberman/quality/metrology/surface.html
3. Volume or mass loss of material over specified time and test conditions. See http://www.gordonengland.co.uk/wear.htm
4. Force per unit area required to remove material from surface - bond strength - Pa
5. Force applied to steel from water. Coefficient of friction.
