The hardness indicates the ability of the material to resist the body's surface. It is one of the important performance indicators of metal materials. The higher the hardness, the better the abrasion resistance. Common hardness indicators include Bud's hardness, Lowl hardness, and Vita hardness.
1. The hardness (HB)
This with a certain load (generally 3000kg) press a certain size (diameter of 10mm) to press hard steel balls into the surface of the material. The ratio of load and its indentation area is the hardness value (HB) of the BBC (HB), and the unit is kg for force/mm2 (n/mm2).
2. Luo Zhi Hardness (HR)
When HB> 450 or the sample is hour, the British hardness test cannot be used to measure the hardness. It is a steel ball with a diamond cone with a top angle of 120 ยฐ or a diameter of 1.59 and 3.18mm. It is pressed into the surface of the tested material under a certain load, and the hardness of the material is found from the depth of the indentation. Depending on the hardness of the test material, there are three different markers ๐ HRA: The hardness obtained by using 60kg load and diamond cone compression is used for materials with high hardness (such as hard alloys, etc.).
HRB: It is a steel ball with 100kg load and 1.58mm diameter.
HRC: It is the hardness obtained by the 150kg load and the diamond cone compression. It is used for materials with high hardness (such as quenching steel, etc.).
3 Victoria Hardness (HV)
The diamond square cone -shaped cone -shaped pyramids with a load of 136 ยฐ within 120kg Press the surface of the material, and the surface area of โโthe material indentation pit is divided by load value. That is the Vilness hardness (HV).
From the above materials, the above hardness is for metal. Can it be used for non -metal? Existing questions should not be.
Mo's hardness is for a variety of different minerals.
Frederich Mohs, a Austrian miners, founded a hardness table as the standard for judging mineral hardness. The softest is talc, the hardest is diamond, and there are ten types of minerals, which are designated as ten levels, which are:
talc (talc) 1
gypsum (GYPSUM) 2
R n Calcite (Calcite) 3
Copper currency 3.5-4
Fluorite (Fluorite) 4
-6
positive stone () 6
Steel
Quartz 7
Huang Yu (Topaz) 8
Diamond 10
The numbers published in the Mo's hardness table have no proportional relationship. For example, the hardness 6 of the positive stone does not mean that he is twice the hardness of the Fangli stone, and the size of the number only indicates the hardness ranking. When the identification hardness, if there is no more than the Mo's hardness meter, it can be replaced by other things, such as the hardness of the small knife is about 5.5; the copper coins are about 3.5 to 4; the nails are about 2 to 3; the glass hardness is 6.
In from the Mo's hardness table, it can be known that the most relative hardness is diamond, and the hardness of Gangyu is greater than steel and iron
Staked scientists will first use chemical evaporation process. The carbon in the gas is precipitated into a small pieces of diamonds, and then these small pieces are decomposed with very high pressure, and then crystallized into a block -shaped diamond with a weight of up to 3 carats.
It never heard of something harder than King Kong Stone (the knowledge is too narrow)
wholesale black jewelry "It can be smashed, although diamonds are the hardest substances in nature, Mo's hardness is 10; but diamonds are relatively crispy (because hardness and intensity are two completely different concepts), they are cut into 57 planes, 2 carats are more than 2 carats or more There are 58 noodles. As long as the hammer can give enough impact, it can completely break the diamond. "
should not be broken on the ground.
mode jewelry wholesale Diamonds are so hard, will it be broken with a hammer to smash the diamond? Listen to what scientists say!

wholesale jewelry gold filled It must be broken. The masonry is the hardest material on the earth, but it is only reflected in scratches and scratches. The masonry can only be cut with masonry, but because of its own structure, I am very afraid of violent impact! The hardness of masonry is not reflected by smashing
jewelry wholesale representative No, diamond is diamond, and the composition element is carbon, which is the hardest stone in the world
