Surface roughness ensures the proper functioning of precision parts, such as seal shafts and friction plates in the automotive industry, and higher surface qualities often result in lower post-treatment costs. Generally speaking, we do not have an absolute good and bad surface roughness, depending ...
The encapsulation of the material avoids the need for manual mixing, the addition of highly reactive smaller particles to the powder strengthens the material, and covering the restoration with a newly developed nanofilled coating material improves its properties [3,5,11]. The newly introduced ...
[4]. These analytical techniques have excellent accuracy, precision, and detection limits, but they have a drawback in that their preprocessing takes a long time and the costs for analysis, constructing the equipment, and maintenance are very high. On the other hand, quantitative analysis methods...
