The phrase "a decrease in coating" is correct and usable in written English.
It can be used when discussing a reduction in the amount or thickness of a coating applied to a surface or material.
Example: "The recent tests showed a decrease in coating thickness, which may affect the product's durability."
Alternatives: "a reduction in coating" or "a decline in coating".
SEM observations of the as-grown coatings combined with roughness measures indicate a decrease in coating thickness (~ 20%) and roughness (~ 30%) while species from the electrolyte accumulate in the outer porous layer simultaneously with a gradual enrichment in α-Al2O3 phase in the inner compact layer (from 36%to4343%).
When effective cutting speeds and feed rates were utilized, optimal tool life was achieved without a decrease in coating properties.
A decrease in coating thickness and a reduction in surface roughness was however observed indicating, a change in coating chemistry.
Higher frequencies generate a decrease in coating electric resistance and in general they are less effective in order to overcome typical critical issues arising in alloys difficult to be anodized.
In this study, we suggest that treatment with crude extracts of aerial parts A. abyssinica has reduced parasite load consequently leading to a decrease in coating of the progenitor cells which prevented or reduced the development of neutropenia.
Improvements in the coating adhesion, H/E ratio and wear resistance were achieved together with a decrease in the coating hardness to 35 45 GPa as the N content in the coatings was increased from 8 to 15 at.%.
It was also found that decreased etching reagent concentration leads to a decrease in HA coating and increased etching time increases HA deposition.
Furthermore, an increase in blood vessel number, size and density associated with a decrease in the pericyte coating have been shown after short-term exposure to LNG-IUS (Stephanie et al., 2007)) and hypothesized to contribute to vascular fragility and BTB (Hickey et al., 2000; Rogers et al., 2000; Jondet et al., 2005).
Moreover, it is observed that deposition efficiency is reduced with a decrease in spray-angle, while the coating porosity and coating roughness show an inverse trend.
The grain size of the TiB2 coating was larger on the nitrided substrates, resulting in a decrease in the hardness of the coating.
The stress concentration induced by coating microdefects was modeled, and was shown to induce a decrease in the cohesive properties of the coating, which correlates with the observed decrease of crack onset strain.
