Metal-To-Metal and Metal Gasketed Seals
SAE Technical Paper Series, 1965<div class="htmlview paragraph">The parameters governing the leakage rate across metal-to-metal and metal gasketed seals are discussed qualitatively and quantitatively based on experimental evidence. The sensitivity of the sealing phenomenon to the surface finish of the mating components is illustrated. The results of several experiments in which

The effects of heavy metals on human metabolism
Toxicology Mechanisms and Methods, 2019As technology continues to advance, heavy metals in drinking water have exceeded recommended limits from regulators around the world. The main source of human exposure to heavy metals is from contaminated drinking water.

Metal allergy and second‐generation metal‐on‐metal arthroplasties
Contact Dermatitis, 2011There are concerns about the induction of metal allergy with second‐generation metal‐on‐metal prostheses, and the role that this may play in the development of complications such as ‘pseudotumours’ or failure of the implant. In this review, we attempt to set out the current knowledge on this subject. From a review of the literature, it is apparent that

METAL/METAL ARTICULATING INTERFACES
Orthopedics, 1995Polyethylene wear can be shown as a problem in long-term joint replacement. Metal-on-metal bearing is solving this problem, as long-term clinical and experimental investigations demonstrate. To avoid the problem of high friction found in old series, a new Metasul called technique with a smaller diameter was invented.

Applications of Surface Science, 1982
Abstract The progress of understanding of the epitaxy of metals on metals achieved in the last decade with improved conventional methods and with surface analytical techniques is illustrated with three groups of film substrate pairs: fcc and hcp metals on W and Mo (110) surfaces.
