Corrosion and Oxide Layer Growth Modeling Using Deterministic and Stochastic Methods
Authors:	Yitung Chen 氏 Professor, Department of Mechanical Engineering, University of Nevada Las Vegas, U.S.A. also...
Summary:	A decade ago it was roughly estimated that a total cost of corrosion of $276 billion has been reported in the U.S. industry. This value shows that the impact of corrosion is approximately 3.1 percent of United States’ GNP in that time. This cost is considered to be a conservative estimate since...
