Adequate softness and surface integrity are the two most important clinical features of a tissue conditioner. This study was designed to examine the effect of coating on the surface integrity and softness of a tissue conditioner at various time intervals. A total of 72 specimens were prepared and divided into two equal groups. Group I (control group) specimens were lined with tissue conditioner...

GH4169, a nickel-base heat-resistant alloy, usually has outstanding high-temperature strength, excellent thermal stability and good wear resistance. However, it is hard to cut and its machined surface quality and integrity are particularly sensitive to a manufacturing process employed. The study reported in this paper was conducted to initially, review existing research on machining-induced sur...

During machining of stainless steels at low cutting -speeds, workpiece material tends to adhere to the cutting tool at the tool-chip interface, forming built-up edge (BUE). BUE has a great importance in machining processes; it can significantly modify the phenomenon in the cutting zone, directly affecting the workpiece surface integrity, cutting tool forces, and chip formation. The American Iro...

The physiological skin surface pH is just below 5. With age the skin surface pH increases up to 6. An increased pH correlates with reduced barrier integrity/cohesion. The present pilot study assesses possible normalization of an increased skin surface pH of the elderly and improvement of barrier function via application of ≈pH 4.0 skin care products. Baseline skin surface pH was determined in e...
