Request a Quote Part # Description Main Unit W3111 3 objectives + 1 indenter, 0.050 - 10kgf load range, includes DiaMet workstation and 24" monitor Software OptionsVickers Hardness The Knoop hardness test is similar to the Vickers test but uses a rhombic-based diamond indenter instead of a pyr-amid. It is commonly used for measuring the hardness of thin coatings or materials with a small indentation requirement. Knoop belongs to the optical methods. Knoop Hardness
Angles of a Knoop hardness test indenter. The Knoop hardness test / k ə ˈ n uː p / is a microhardness test – a test for mechanical hardness used particularly for very brittle materials or thin sheets, where only a small indentation may be made for testing purposes. A pyramidal diamond point is pressed into the polished surface of the test material with a known (often 100 .In the Knoop hardness test, an optical method, the size of indentation left by the indenter is measured. The larger the indent left by the indenter at a defined test force in the surface of a workpiece (specimen), the softer the tested material.The Knoop hardness test method, also referred to as a microhardness test method, is mostly used for small parts, thin sections, or case depth work.The Microhardness test procedure, ASTM E-384, specifies a range of light loads using a diamond indenter to make an indentation which. The Knoop hardness test is a microhardness test designed for brittle materials like ceramics and glass, as well as for small or thin metal sections. . Proper calibration: Regularly calibrate the hardness testing machine with certified reference materials. Calibration helps in maintaining the accuracy of the measurements over time.

Similar to Vickers hardness testing, Knoop uses a diamond .The hardness numbers shall be followed by the symbol HV for Vickers hardness, or HK for Knoop hardness, and be supplemented by a value representing the test force in kgf. Examples: 450 HV 10 = Vickers hardness number of 450 obtained with a test force of 10 kgf, 700 HV 0.1 = Vickers hardness number of 700 obtained with a test force of 100 gf (0. .
Vickers versus Knoop hardness testing In most cases, the Vickers hardness test is used to determine hardness in materials in the micro hardness test load range. However, the Knoop hardness test is often used when hardness testing thin layers, such as coatings, or to overcome the problem of cracking in brittle materials.Knoop Hardness Test: Similar to the Vickers test, but with a more elongated diamond-shaped indenter. It’s preferred for thin materials or small parts due to its ability to generate tiny indentations. . This method finds utility in scenarios where conducting a static hardness test (typically performed on a testing machine) might be .LECO offers a wide selection of hardness testing systems to match any application or budget.
