This article mainly introduces a hardness test of the 6061 aluminum tube in metal testing and some methods used in the process. It is well known that for the metal testing method, the country currently implements six national standards, and in these six national standards, all the soft and hard metal testing methods are included, and in the specific experimental testing behavior, six sets of national standards are divided into two. One type of test, one is static test force, and the other is dynamic experimental force. The 6061 aluminum alloy dynamic test force national standard can test the hardness of some relatively large industrial workpieces. After extending the application range of the hardness test method, the basic principle of the aluminum alloy metal hardness test is to resist with a material. Another kind of hard material's ability to press in, the angle can be said to be the local deformation of the material, the key is the plastic deformation of the aluminum alloy and the ability to slide the pressure. Hardness is the main basis for judging the hardness of the metal. The test of the alloy aluminum plate can evaluate the difference in the process performance of the metal after heat treatment.
In order to ensure the effect of different metal alloy elements on the surfacing metal, the 6061 aluminum tube utilizes 12 kinds of alkaline coating surfacing electrodes, which are matched with photoelectric reading spectrometer and Rockwell hardness tester. Filling the composition and hardness as an evaluation work. The hardness of 6061 aluminum alloy surfacing metal can be traced under the influence of alloy transition characteristics of C, Ti, Nb and V elements. The test report of the 6061 aluminum tube can be known that the element of c has a large influence on excessive volatility. Moreover, in a professional test, a hardness is generally used to evaluate the wear resistance of a weld layer, because wear-resistant surfacing is an optimized process for the surface of materials that is often used in engineering. Of course, hardness is a very high degree of wear resistance. Important elements, and it is easier and easier to test.
