Surface Engineering Measurement Standards for Inorganic Materials (SP 960-9 By Stanley J. Dapkunas, Materials Science and Engineering Laboratory U S Dept of Commerce, Technology Admin Publisher: U.S. Department of Commerce Carlos Gutierrez, Secretary, Technology Administration Phillip J. Bond, Under Secretary for Technology National Institute of Standards and Technology Hratch G. Semerjian, Acting Director Special Publication 960-9 NIST Recommended Practice Guide Number Of Pages: 264 Publication Date: April 2005 Surface engineering of materials is important in applications as diverse as medical implants and gas turbines. Historically, a coating or cladding was added to a surface, or a surface was treated, to enhance properties or performance. However, increasingly, heat treated, implanted, coated and clad surfaces are viewed as part of a materials system where the substrate and surface complement each other in achieving a performance goal for a component. The integration of the surface and substrate as an engineered system creates a situation where failure of the surface may, in effect, be failure of the system and thus characterization of surfaces and measurement of surface properties are important to the design, maintenance, and analysis of the whole system. The advantages of engineered surfaces have stimulated development of surface treatment and coating processes as well as materials and, consequently, commerce. Commerce in engineered materials depends upon the ability to specify and measure composition, microstructure, dimensions and properties as well as performance in applications of interest. The intent of this Guide is to give the materials community a resource for identifying standard methods which are used to measure surface properties and to characterize surface engineered materials. 支持就顶一下! http://rapidshare.com/files/53996575/_R20070815R.rar [ Last edited by universemaster on 2007-9-24 at 21:41 ] |
