ASTM B796 – Standard Test Method for Nonmetallic Inclusion Content of Ferrous Powders Intended for Powder Forging (PF) Applications Description: Significance and Use 4.1 The extensive porosity present in pressed and sintered ferrous materials masks the effect of inclusions on mechanical properties. In contrast, the properties of material powder forged to near full density are strongly …
ASTM B769 – Standard Test Method for Shear Testing of Aluminum Alloys Description: Significance and Use 5.1 The intent of this method is to provide a means of measuring the ultimate shear strength of aluminum-alloy wrought and cast products. Data obtained by this method are used to calculate minimum properties that can be utilized in the …
ASTM B767 – Standard Guide for Determining Mass Per Unit Area of Electrodeposited and Related Coatings by Gravimetric and Other Chemical Analysis Procedures Description: Significance and Use 4.1 The thickness of a coating is critical to its performance and is specified in many specifications calling for coatings. 4.2 These procedures are used for acceptance testing and appear …
ASTM B764 – Standard Test Method for Simultaneous Thickness and Electrode Potential Determination of Individual Layers in Multilayer Nickel Deposit (STEP Test) Description: Significance and Use 4.1 The ability of a multilayer nickel deposit to enhance corrosion resistance is a function of the difference in the electrode potentials of the nickel layers (as measured individually at …
ASTM B761 – Standard Test Method for Particle Size Distribution of Metal Powders and Related Compounds by X-Ray Monitoring of Gravity Sedimentation Description: Significance and Use 4.1 This test method is useful to both producers and purchasers of powders, as outlined in 1.1 and 1.2, in determining particle size distribution for product specifications, manufacturing control, development, and research. 4.2 Users …
ASTM B748 – Standard Test Method for Measurement of Thickness of Metallic Coatings by Measurement of Cross Section with a Scanning Electron Microscope Description: Significance and Use 4.1 This test method is useful for the direct measurement of the thicknesses of metallic coatings and of individual layers of composite coatings, particularly for layers thinner than normally …
ASTM B735 – Standard Test Method for Porosity in Gold Coatings on Metal Substrates by Nitric Acid Vapor Description: Significance and Use 5.1 Gold coatings are often specified for the contacts of separable electrical connectors and other devices. Electrodeposits are the form of gold that is most used on contacts, although it is also employed as …
ASTM B721 – Standard Test Method for Microhardness and Case Depth of Powder Metallurgy (P/M) Parts (Withdrawn 2004) Description: Scope 1.1 This test method covers determination of the microhardness of powder metallurgy (P/M) parts and applications of microhardness test results to methods for determination of the case depth. Technique for measurement of case depth of …
ASTM B695 – Standard Specification for Coatings of Zinc Mechanically Deposited on Iron and Steel Description: Abstract This specification covers the requirements for zinc coatings that are mechanically deposited on iron or steel basis metals. The zinc coatings are classified according to thickness and identified into two types; as coated without supplementary treatments or with …
ASTM B680 – Standard Test Method for Seal Quality of Anodic Coatings on Aluminum by Acid Dissolution Description: Significance and Use 3.1 This test method describes a destructive test procedure for measuring the degree of seal of the porosity in anodic oxide coatings. Low coating mass loss is an indication of good seal quality and of …
