Why The Demand Of Rockwell Hardness Test Is Steadily Growing In The Market?

 Hardness tests assess the resistance a raw material subject to permanent deformation by penetration of another hard material. It evaluates the material properties, such as strength, ductility and provide useful information to the users whether a material or material treatment is suitable for the purpose required.

From a manufacturing or maintenance viewpoint, hardness is of great importance given the fact that resistance to deterioration through the medium of friction or erosion (by water vapour, greasy liquid, and water) escalate with hardness.

Hardness is generally calculated using three fundamental categories of hardness estimations, scratch, indentation, and rebound. Inside each hardness estimation type, there are customized measurement scales.

Indentation hardness calculates the resistance of a specimen (of a raw material) to permanent material distortion owing to a continuous compression load from a sharpened item.

In a Rockwell hardness test, the hardness of the raw material is ascertained by first exerting pressure on the article (whose hardness is being established) with the help of an indenter containing a predefined force and later, by gauging the indentation depth.

Rockwell hardness test has the upper hand in the marketplace because of its competitive advantages like:

·   The Rockwell hardness test is rapid, cheap, and non-destructive, creating a minor indentation impression in the raw material.

·       Normally, does not call for a highly trained operator.

·       Viable automated testing alongside speedy testing time and exact results

·       This testing method can be used on almost all metals, including exceptionally hard substances.

The sole process to permit prompt reading of the hardness value, omitting optical reading.

Use of Ultrasonic Testing in the Power Generation Industry

Ultrasonic testing is a method used for determining the thickness of a structure with the help of sound waves. These sound waves are of high frequency, and this method is a reliable non-destructive method used in the power generation industry. There is no need to cut the test piece or use any chemical that might deteriorate it. The sound waves travel through the surface of even sturdy metals and help determine the thickness.   How does Ultrasonic Testing work? High-frequency sound waves that are way beyond the limit of the human ear get induced in this non-destructive testing technique. The test is performed under the supervision of an expert only. They can do the setup with proper requirement standards. Devices are used to induce the sound waves into the material in question. These sound waves can penetrate through any surface except for paper or wooden products. After passing through the surface, the sound wave is reflected when hitting the boundary and is returned to the so

What does paint thickness gauge do, and how is it useful?

A coating thickness gauge, also known as paint thickness gauge or paint meter is used to measure thickness of the dry film. Dry film thickness is the most complicated thickness measurement in the entire coating industry because of its impact on the quality, coating process, and cost. Such measurements can be used to evaluate the expected life of the coating, the appearance, and the performance of the product. The measurement further ensures the compliance of the product with all the international standards. A paint thickness gauge uses different principles and mechanisms, and the ultrasonic principle is one of them. This technique is used for measuring the thickness of the paint on all the non-metal substrates like fiberglass and plastic. The probe of the instrument comprises an ultrasonic transducer that works by sending a pulse throughout the coating. This pulse then reflects from the substrate to the transducer and is further converted into a high-frequency electric signal. It is t

What are the advantages of eddy current testing?

  Different industries perform various testing techniques to infer details like identifying product flaws, measuring material thickness, detecting metals, and more. Many significant decisions related to production depend on this information. Hence, they take it very seriously. However, most industrial experts opt for non-destructive techniques like eddy current testing as they are safe and reliable.  What is eddy current testing? This technique is ideal for testing conductive materials with the help of the electromagnetic induction principle. The magnetic field is built around the material under investigation that oscillates to develop the alternating current into the coil that induces current into the specimen. The change in conductivity of the material due to the induction of eddy currents allows the experts to interpret the data and identify defects. For example, it will help know the thickness, check for flaws inside the metal and other condition information. Advantages of u
