How to identify the advantages and disadvantages of the Richter hardness tester?

Richter hardness tester is a test equipment,its basic principle is to have a certain quality of impact body under the action of a certain test force can impact the surface of the specimen,measuring the impact body from the surface of the specimen 1mm at the impact speed and jump back speed,you can utilize the electromagnetic principle,the induction and the speed of the proportional voltage.Different manufacturers of the Richter hardness tester in the quality is certainly there will be some differences,specifically how to determine the advantages and disadvantages of the Richter hardness tester,we can be determined by the following methods.

The three main types of hardness measured by a hardness tester

The hardness tester is mainly used for hardness testing of forged steel and cast iron with uneven organization.The hardness of forged steel and gray cast iron has a good correspondence with the tensile test.It can also be used for non-ferrous metals and soft steels,and the use of a small diameter ball indenter allows the measurement of small sizes and thinner materials.

Scope of application of Vickers hardness tester

The Vickers hardness tester has a relatively large number of test forces,as long as the roughness of the surface of the workpiece meets the measurement criteria,the Vickers hardness tester can test.Vickers hardness tester through the stepping motor,on the surface of the workpiece pressure,and then by reading microscope to measure the length of the diagonal of the indentation.Afterwards,the diagonal and the test force of a conversion relationship to measure the Vickers hardness.In addition,you can install the Vickers hardness tester measurement software,through the computer display to show the image,so that the operation of the measurement of the hardness value is more convenient and faster.

Rockwell hardness tester use methods and precautions

Digital Rockwell hardness tester only need one-sided contact specimen can test metal hardness,relying on magnetic force Rockwell hardness tester head adsorption on the surface of steel,do not need to support the specimen,can be said to be more convenient.So what do you need to pay attention to when using the digital Rockwell hardness tester?The following small editorial take you to understand.I hope you can help.

Select Rockwell hardness tester by material type

The hardness test of hardened and tempered steel is mainly conducted using the HRC scale.If the material is thin,it is not suitable to use the HRC scale,you can use the HRA scale.If the material is thinner,you can use the surface Rockwell hardness tester HR15N,HR30N or HR45N scale.

Durometer use precautions of its own factors

1,the hardness tester itself will produce two kinds of errors:one is the deformation of its parts,the error caused by the movement;the second is the hardness parameters beyond the prescribed standard caused by the error.For the second kind of error,the hardness tester needs to be calibrated with a standard block before measurement.Rockwell hardness tester calibration results,the difference in±1 within the qualified.Difference in±2 within the stable value,can give the correction value.Difference in the±2 range outside the hardness tester must be calibrated maintenance or other hardness test method for determination.
