The surface roughness of enamel coating and its bond strength over steel pipe substrates were determined.
Wear resistance. Electrical resistance,brihgtness, surface roughness.;• Non-electrochemical methods of metallic coatings deposition.
The surface roughness of enamels and their bond strength with steel substrates were quantified to understand coating quality.
Since it says the height of imperfection,I think it should be surface roughness in the technical specification of bearing balls.
Steel castings surface roughness is an important factor in the quality detection of stainless steel castings, such as….
Cutting surface smooth: cutting surface without burr, cut surface roughness is generally controlled within Ra12.5.
The surface roughness of 0.008 um Ytterbium alloy can be obtained by this technology, which is the highest among all polishing methods.

Pull-Off Strength- The measured thickness, surface roughness, and bond strength of three types of coatings are summarized in Table 4.
Surface roughness: surface irregularities with relatively small spacings, which usually include irregularities resulting from the method of manufacture being used and/or other influences.
Cutting surface smooth:cutting surface without burr, cut surface roughness is generally controlled within Ra12.5.
Wind farms increase surface roughness and therefore increase wind converging into low-pressure areas,” said Dr Li.

Seal ring: seal ring face's flatness≤0.0006MM, seal ring‘s surface roughness≤0.1μm, seal ring face without crack, scratch, pore and so on.
The increased porosity and changes in surface roughness may have an impact on the formation of supra- and subgingival plaque, thus increasing the adhesion of bacterial species such as Streptococcus mutans and Streptococcus sobrinus, significant contributors to dental cavities.[3] Dental restorations are susceptible to unacceptable colour change even when using the home-based systems.[4].
In the classification category above is of steel cold-rolled flat steel, it had better steel andcold-rolled flat steel on steel surface roughness is better, and the intensity of precipitation hardening stainless steel is relatively high, no longer need to be heat treated to get a higher strength.
Paint plate surface is polished, the surface roughness is high, mirror effect is also very good, this material is made out of the cupboard with bright colour, extravagance, gives people a visual impact of light.
Dušan Skakić used certain resources of the Institute for Furniture Quality Control to purchase modern equipment for testing the quality of painted surfaces( surface roughness determination, determination of dry film thickness of the coating with and without destruction, testing of the thickness of hardened film coating; determining of the gloss of lacquered surface; determining of a hardened coating adhesion).
