Tech Showcase: Which Hardness Test Works?

Used to check material uniformity or processing treatment, most hardness tests employed in quality control applications yield numerical values based on a material’s resistance to indentation under the conditions imposed by the particular test. Resistance to scratching and the measurement of the amount of energy absorbed by a material when struck by a falling object also are measures of hardness.

NDT Applications: Helium Leak Tested Integrity

Titan Metal Fabricators Inc. (Camarillo, CA), a designer and manufacturer of heat exchangers, pressure vessels and related products for the steel, pharmaceutical and chemical industries, was commissioned to construct a 90-foot-long, 5-foot-diameter pressurized column for a customer. The column was to be used for the containment of pressurized hydrochloric acid at a high temperature. Before the column could be delivered to the field, it had to undergo leak testing that would verify its conformity to applicable requirements of the American Society of Mechanical Engineers (ASME) and stringent customer demands.

NDT Back to Basics: Radiographic Technologies

For more than a hundred years, industrial manufacturers have been using film-based radiographic techniques (RT) for a full range of inspection needs, from aircraft testing to weld qualification. But in today’s digital world, radiographers are seeking more efficient methods of accomplishing the inspection cycle by using computed and digital technologies for nondestructive testing.

Ultrasonics Offers Flexibility

Whether for quality control in the manufacturing environment or for ensuringthe integrity of in-service structures or components, in all sectors of industry,accurate, reliable and repeatable inspection is a vital tool. There are manyinspection modalities and no single technique offers a comprehensive solutionto all inspection needs. However, ultrasonics is probably the most flexible of all modalities.

Scratch Test

The new ASTM standard for scratch adhesion testing, ASTM C1624, covers the determination of the adhesion strength and failure modes of hard, thin ceramic coatings on metal or ceramic substrates. Scratch testers can be used for industrial quality control as well as scientific research. They should allow both lightly skilled operators and more experienced personnel to use the instrument to characterize the mechanical properties of Physical Vapor Deposition (PVD) or Chemical Vapor Deposition (CVD) coatings.

Measuring the Ductility of Metals

Ductility is defined as the ability of a material to deform plastically before fracturing. Its measurement is of interest to those conducting metal forming processes, to designers of machines and structures, and to those responsible for assessing the quality of a material as it is being produced.

Tech Showcase: The Right Borescope

Industrial borescopes generally fall into two categories: rigid borescopes and flexibleborescopes, also known as fiberscopes. The type of borescope employed is contingenton the application. These devices are used in a number of industries to attainquality assurance, enabling inspection for manufacturing defects withoutnecessitating part destruction. They also are used in equipment maintenance programs,eliminating the need for teardowns when checking for defects.
