The results will be different if you choose the wrong test and the wrong equipment for the test. For measuring the hardness of the pencil, a simple graphite pencil is used.
Copper plays an important role in the life of human beings. From the delivering of electricity to the supply of water, copper made all things possible. It allows the electric current to passes through it with the same voltages; it is the good conductor of electricity. The copper is used in the electric appliances, almost every high-quality motors have the copper wires in them. In the past, the cutlery item is made from the copper with are a good conductor of the heat and cold. Copper itself is soft in nature but when you mix it with any other metal it becomes hard.
The hardness of the material gives it the ability to resist permanent deformation when the load is applied. From an engineering point of view, determining the hardness of the material is important because resistance to wear by erosion or friction by different elements tends to increase with hardness generally. The greater would be the ability of the material to resist deformation as greater it would be its hardness.
Pernahkah anda tertanya-tanya apa perbezaan antara penguji kekerasan Rockwell, penguji kekerasan Vickers, dan penguji kekerasan Brinell?
But what does hardness actually mean? Despite popular conception, or rather misconception, it certainly does not indicate toughness of a material or substance. Diamond, which is the hardest, would most certainly crack if hit with a hammer. Steel, on the other hand, would not.
There are several hardness tests available in the market according to the type of test, the material of indenter, the type of sample, etc. Since the past few decades, there has been a surge in the market for the hardness testers.
What is the Brinell hardness method? Brinell hardness method is an optical method that works by measuring the intensity of indentation that is caused by an indenting material. Brinell hardness method applies an indenter that is spherical in shape, unlike the Vickers...
After a metal has been cast in the foundry, it is really necessary to test its hardness. Therefore, after casting metals, the next thing before they are used is a hardness test. After the test, the result reveals the following information, among other things, as regards the material:
Diamonds are made of carbon atoms that each have 4 electrons within them. These electrons bond with the electrons of another carbon atom and so on and so forth. This results into diamonds exhibiting their characteristic hardness.
