Metallographic Sample Preparation

Metals, ceramics, sintered carbide, and other solid materials often require metallographic sample preparation to reveal the true structure of the material. Understanding both hardness and ductility of the material is key to choosing the right preparation method. A solid understanding of proper mounting, cutting and polishing samples and the interdependencies of these three steps requires skills and knowledge in material properties and the techniques used.

Proper mounting of samples is needed during the cutting and polishing steps of preparation to keep the integrity of small, delicate, or brittle materials. This proper mounting ensures that the cutting and polishing sample preparation steps provide optimum conditions for SEM and EDS analysis.

Mounting

We mount samples in a cold mount with a 2-part epoxy typically using a 1” diameter mold.  We carefully match the material properties of the epoxy such as shrinkage, cure time, viscosity, and adherence with the sample properties such as hardness & ductility, to provide for optimal cutting and polishing conditions. Once a sample is mounted and the epoxy is properly cured, cutting exposes the plane of intertest, if it is not already exposed.

Cutting

We offer cross sectioning, leveling, or exposing internal features when sample’s area of interest is not revealed.

Our precision cutting technique combined with blade size, type, sample temperature monitoring, force and speed are independently reviewed and evaluated to ensure sample integrity.

Our extensive experience in material science and material properties, such as such as ductility, brittleness, and hardness drive our recommendations to prepare your samples.

Polishing

We provide multi-step grinding and/or polishing of samples after proper mounting to generate deformation-free, scratch-free and highly reflective samples. The sequence of polishing, the materials selected, and the time spent polishing samples largely depend on the type of sample.

Polishing time, and abrasive media are selected are recommended based on your sample’s properties, including ductility and brittleness. We utilize abrasive paper with different grit sizes, diamond paste, alumina powder, or silica powder solution to prepare samples for the desired polished outcome.

If a smoother surface is required beyond mechanical polishing, ion milling is utilized to achieve the desired polished surface.
