For over 80 years, Buehler has been manufacturing and selling the world\u2019s highest quality and most durable metallographic sample preparation machines and consumables. Buehler continues this tradition of quality today by manufacturing Wilson Micro-Hardness testers and Macro-Hardness testers.<\/p>\n

Micro-Hardness Testing Background<\/h3>\n

In the world of micro-hardness testing, Knoop and Vickers are the two main practices used to take measurements – both leave different and unique indentations in the material. Depending on your application, you will need to know when to use Vickers, and when to use Knoop.<\/p>\n

Vickers measurements have symmetrical indents, making it easier for positioning and repeatability. However, if you have tried taking a hardness measurement on a thin coating or layer, you may realize that measuring in Vickers may not be effective. Knoop is designed to offer the ability to put more closely spaced indents in a staggered array. The difference between both Knoop and Vickers indentations is illustrated below in Figure 1. Both Knoop and Vickers can be supported in all Wilson Micro-Hardness Testers.<\/p>\n
