Grinding and polishing are two different but related steps in getting materials ready. Grinding gets rid of surface flaws and makes uneven areas flat. Polishing makes the surface look better by giving it a smooth, shiny gloss. From our workshop experience, we know that to becoming good at both techniques, you need to know what […]
As up to 80% of mistakes can be traced back to bad sample preparation, when preparing metals for analysis the quality of the polishing cloth is basically what makes or breaks the whole process. Here at Metkon, we’ve made it our mission to master the art of metallographic polishing and now offer polishing cloths that […]
In terms of mounting metallographic samples, the introduction of phenolic thermosetting plastics in ’28 completely changed the face of the industry, by giving us a reliable way to encase the specimens, though initially, it wasn’t exactly sophisticated. Coming into the ’50s, castable resins took the industry to new levels, and enabled us to adjust the […]
The science of petrology comes to the forefront, with its systematic description and classification of rocks being the backbone of modern geological investigation, when delving into the mysteries of the Earth. Since its inception in the 19th century, the methodical approach of petrography has completely altered our comprehension of rock formations, mineral compositions and geological […]
Human errors that occur in the lab can be a major issue, and even the most highly qualified personnel can have a bad day or be out sick, affecting the consistency of the outcome, when preparing samples for metallography. Automated systems help in significantly reducing these problems, and when we look at the scale of […]
The quality and precision of your results largely depend on the quality of your Metallography Consumables, something that even the best equipment cannot compensate for, when preparing metallographic specimens. Cutting discs, mounting resins, grinding papers, and polishing cloths all play a crucial role in this process and getting them right can take an average surface […]
Portable Metallography testing has changed the way we measure material properties in the field. No longer do samples need to be taken back to research labs. Over the past few years, specialists have devised methods of testing small specimens as well, and today they are generally considered the leading authority in this specialized area worldwide. […]
Hardness conversion charts serve as essential tools for engineers and metallurgists working across different material testing standards. Converting between Rockwell, Brinell, and Vickers scales often creates significant challenges in manufacturing and quality control environments. Without accurate conversions, material specifications can be misinterpreted, potentially leading to component failures or rejected parts. Download Metkon Hardness Conversion Table […]
Consistency and quality of results are a challenge in metallographic sample processing. Selection of suitable grinding material is a major factor to success in your analysis. Diamond grinding disks excel at cutting efficiently and lasting longer as they are diamond abrasives bonded on metal or resin backings. There are multiple factors that influence the performance […]
Metallographic grinding machines play an essential role during the final and key part of the sample preparation process. Once ground and polished, the surface of your sample is very good. These processes ensure that you obtain a deformation-free, scratch-free and highly reflective surface of the specimen to conduct accurate microstructure analysis. Research results can be […]
