They evaluate and test many different types of parts. They may have our people just focus on the 3 most popular part types. Using saws, grinding, polishing, mounting and evaluation. They will probably have us doing the "lab" portion (preparing the samples with saws, grinders, polishing, and mounting). They will probably keep the scope analysis portion running with their people. The grinders/polishers are automated. Load parts and run from a computer console. Either large industrial saws, or smaller saws used for cutting. Cutting to specified dimensions. All saws have proper shielding in use. Cutting blades, nozzles, vanes, tabs, or coupons. Hot and cold mounting processes. One type is done with a press, the other is more hands on with epoxy. Easily trained if they previous mounting experience. Microscope - evaluate multiple areas out of 1 sample. Various measurements of the samples. They will probably handle this themselves, but if people have scope analysis experience, they may utilize them. 3 types of coatings; diffusion or bond coatings, thermal barrier coatings, and plasma coating, which is like thermal spray, but different. They will train them on different coatings, but experience would be best. We will not be doing oxidation work. They will probably handle all documentation into their quality system (Oracle).

Purpose:

The primary goal is to handle samples safely and efficiently during preparation, ensuring they remain flat and protected during examination. Hot Mounting (Compression): Involves heat and pressure (typically 150∘C150∘C-180∘C0∘C) to cure thermosetting resins like phenolic or epoxy. Best for high-volume, rugged samples requiring superior edge retention. Cold Mounting (Castable): Uses two-part systems (resin and hardener) that cure at room temperature without pressure. Ideal for sensitive, fragile, or porous materials that cannot withstand heat.

Mounting Materials:

o•

Epoxy:

Low shrinkage, excellent adhesion, ideal for high-precision, transparent mounts.• o•

Acrylic:

Fast curing and easy to use.• o•

Phenolic:

Cost-effective, commonly used for routine, dark-colored mounts.•

Process:

Samples are cleaned, placed in a mold, and the resin is added and cured before being polished. Basically preparing the material for microscope inspection.
