Surface Roughness 测试 with 3D Optical Profilometry

im体育APP's surface roughness testing uses 3D optical surface profilometry for measuring the surface roughness of components. Surface measurement of elevations and discontinuities is required for quality pass control of highly smooth surfaces and the characterization of surface defects. 

Many components and products require a certain surface smoothness for their full functionality. Surfaces that are too rough can affect the flow of 气体es or liquids, 的光泽, even the acoustic and mechanical properties of a component. The smoother a surface, the higher the manufacturing effort and cost, as a rule. We help our clients during the R&D stage and quality control to find the balance between tolerable surface roughness and costs. 在操作, undesirably rough surfaces indicate friction, which can cause components to wear out more quickly. Surface discontinuities and roughnesses are also common at sites where defects are prone to nucleate, the suitable characterization and determination of these are crucial.

With contactless optical profilometry, im体育APP helps to improve the effectiveness and efficiency of surface examinations and analyses. It can be used for almost any kind of solid materials and offers advantages in terms of speed, 精度, surface integrity over other surface inspection methods like optical microscopy, scanning electron microscopy (SEM), contact profilometers, or calibrated gauges. 

Practical applications of optical profilometry

The equipment provides quantified 3D characterization for a wide range of surfaces, from rough to smooth, 从硬到软, 胶粘剂, deflectable, or otherwise difficult to measure. Typical applications of surface profilometry and analyses are:

• Determination and analysis of 腐蚀 pit dimensions (diameter, depth)
• Determination of microscopic particles dimensions over a substrate/surface (e.g., particles characterization, contaminants
• Wear pattern visualization and quantification
• Roughness measurements, including rounded surfaces
• Determination of thread dimensions (for threading heights <10mm) 
• 涂料 depth and defects measurements
• Dimensioning of microscopic fractographic features
• Determination of surface roughness and defects of fatigue tests
