GB/T 11376-2020 Translated English of Chinese Standard (GB/T 11376-2020, GBT11376-2020)


Book Description

This Standard specifies methods for determining the requirements for phosphate conversion coating. This Standard applies to ferrous materials, aluminum, zinc, cadmium and their alloys (see Appendix A).




Coatings and Coating Processes for Metals


Book Description

A reference work covering commercial coating processes. Coating types covered include organic coatings (paints) and their process cycles, electroplating, vacuum deposition coatings, electroless plating, and conversion coatings. The bulk of the book is taken up with an alphabetical listing of 2,000




Testing of Metallic and Inorganic Coatings


Book Description

Coatings are tested to confirm compliance with specifications, to monitor the operation of a coating process, and to evaluate coatings for various services. The ability of a coating to perform as intended usually depends on several characteristics, and the testing of a coating usually involves several different tests. At first glance the nature of a characteristic that is being tested may seem clear and the results of a test may seem to be unambiguous, however, the nature of a characteristic my be more complex than realized and the ability of a test to measure the characteristic may be less than expected. The members of the ASTM Committee B-8 on Metallic and Inorganic Coatings felt it was desirable to organize a symposium on the testing of the metallic and inorganic coatings so as to bring these problems to the attention of practitioners. This publication is based on the symposium, which was presented in Chicago on April 14 and 15, 1986.




GB/T 9799-2024 Translated English of Chinese Standard (GB/T 9799-2024, GBT9799-2024)


Book Description

This document specifies the requirements for treated zinc electroplated coatings on steel, including the information to be provided by the purchaser to the supplier and the requirements for heat treatment before and after electroplating. This document does not specify the surface condition of the base metal before zinc electroplating, but defects on the base metal surface will have an adverse effect on the appearance and performance of the coating. This document applies to treated zinc electroplated coatings on iron or steel. This document does not apply to: -- zinc electroplated coatings on unformed steel sheets, strips and wires; -- zinc electroplated coatings for tightly wound springs; -- zinc electroplated coatings for non-protective decorative purposes. The thickness of the electroplating coating on threaded parts can be limited by thread grade or assembly size requirements.







Hot-Dip Galvanizing of Steel Structures


Book Description

Hot-Dip Galvanizing of Steel Structures contains practical information that is useful for both researchers in hot-dip galvanizing and engineers, designers, and inspectors. The book draws from the empirical experience and research of the authors, complementing the current state of knowledge of morphological variations of the coating and causes of coating delamination. The book includes chapters devoted to qualitative tests of the coating, and to methods of making corrections. A section describing the principle of protecting steel against corrosion through zinc coating is also provided, along with an extensive chapter on the principles of good design for hot-dip galvanizing. The chapter related to the safety of hot-dip galvanized steel structures offers a new hypothesis about the mechanism of nucleation of LMAC cracks during hot-dip galvanizing, thus enriching the knowledge regarding this phenomenon. - Provides practical information on hot-dip galvanizing from a scientific-disciplinary perspective, including coverage of design principles, reliability of galvanized structures, and legal aspects - Features chapters devoted to qualitative assessments of the surface treatment and methods for correcting problems - Includes discussion of hot-dip galvanizing with regard to environmental aspects and sustainable development
