GENERAL GEOLOGY

Detailed explanation-1: -Positive material identification (PMI) is used to analyse and identify material grade and alloy composition for quality and safety control. A rapid, non-destructive method, positive material identification is performed on a wide range of components and assets, and provides a semi-quantitative chemical analysis.

Detailed explanation-2: -Positive material identification (PMI) is essential to verify the grade and composition of stainless steel before releasing into production. Using the wrong grade can damage machining equipment, result in field failure or flout industry regulations.

Detailed explanation-3: -Positive Material Identification (PMI) is a fast and non-destructive testing (NDT) method for verifying the chemical composition of metals and alloys. PMI can be used to verify that supplied materials conform to the proper standards and specifications.

Detailed explanation-4: -Particles sprayed onto a substrate held at room temperature form splats that are extensively fragmented; preheating the surface above a critical temperature, known as the transition temperature (T t) results in disk-shaped splats.
