# MIL-P-83348 Testing

## Do you need to validate the compliance of your thermal spray powders according to MIL-P-83348?

### Securing surface coating performance with MIL-P-83348 requirement

In the [Aerospace](https://filab.fr/en/sectors-of-activity/laboratory-analysis-aeronautics-aerospace.md), [Space](https://filab.fr/en/sectors-of-activity/laboratory-analysis-aeronautics-aerospace.md), and [Defense](https://filab.fr/en/sectors-of-activity/laboratory-analyses-tests-defense-security-sector.md) (ASD) sectors, thermal spray coatings (plasma, HVOF) are essential for protecting components against [wear](https://filab.fr/en/our-services/our-expertise-services/laboratory-analysis-failures/laboratory-analysis-wear.md), heat, and[corrosion](https://filab.fr/en/our-services/our-expertise-services/laboratory-analysis-deposit-contamination/laboratory-expertise-and-analysis-of-corrosion.md). The quality of the final [coating](https://filab.fr/en/our-services/our-expertise-services/electrochemical-characterization/anticorrosive-coating-analysis.md) depends directly on the intrinsic properties of the [powder](https://filab.fr/en/our-services/our-analysis-services/laboratory-analysis-powder-characterization.md). Any deviation can impact the durability of your **essential parts.**

The **MIL-P-83348** military specification defines requirements for [metal powders](https://filab.fr/en/our-services/our-analysis-services/laboratory-analysis-powder-characterization/metallic-powders-characterization-services-at-filab-laboratory.md) ([Nickel](https://filab.fr/en/our-services/our-analysis-services/metallurgical-analysis-laboratory/laboratory-analysis-nickel-alloys.md), [Cobalt](https://filab.fr/en/our-services/our-analysis-services/metallurgical-analysis-laboratory/laboratory-analysis-cobalt-alloys.md), [Chrome](https://filab.fr/en/our-services/our-analysis-services/metallurgical-analysis-laboratory/laboratory-analysis-chromium.md) alloys, etc.) used for protective coatings. It imposes strict controls on[chemical composition](https://filab.fr/en/our-services/our-analysis-services/metallurgical-analysis-laboratory/metallic-alloy-analysis-laboratory.md), [particle size distribution](https://filab.fr/en/our-services/our-expertise-services/laboratory-analysis-particulate-contaminant/laboratory-for-particle-size-distribution-analysis-according-to-iso-17025.md), and particle [morphology](https://filab.fr/en/laboratory-analysis-powder-morphology.md) to guarantee optimal melting during spraying.

At **FILAB**, we support applicators and powder manufacturers in the ASD supply chain with the qualification of their materials according to MIL-P-83348, with a clear goal: to ensure the reliability of your technical and industrial decisions.

### MIL-P-83348: a flowability and purity challenge

### Thermal spray powder compliance control according to MIL-P-83348

Compliance with this requirement guarantees that the powder will behave predictably in the spray torch and that the deposit will exhibit the expected hardness and adhesion characteristics.

It is specifically used to:

- **Verify chemical composition** by ICP-OES to guarantee alloying element content and limit impurities.
- **Analyze particle size** (often by laser diffraction or sieving) to ensure the size is adapted to the spraying process.
- **Characterize grain morphology** (sphericity, internal porosity) which directly influences final coating density.

 

In the Aerospace and Defense industries, compliance with MIL-P-83348 has a direct impact on:

- **Thermal resistance** of thermal barrier coatings (TBC) in engines.
- **Wear protection of landing gear** and transmission shafts.
- **Interface quality** between the substrate and the coating to avoid spalling.

## Our FAQ

 What types of alloys are commonly tested under MIL-P-83348?
We mainly find **Nickel-based** powders (Nickel Aluminides), **Cobalt-based** (Stellite), or **MCrAlY alloys** used as **bond coats** for thermal barriers.

 Why is particle size so precise in this requirement?
If particles are too fine, they evaporate or overheat in the plasma jet. If they are too coarse, they do not melt completely, creating **"unmelted particles"** (or unmelts) in the coating which weaken its properties.

 Can FILAB measure oxygen in these powders?
Yes, Oxygen and Nitrogen determination is crucial because an overly oxidized powder loses its adhesion capabilities. We use **Inert Gas Fusion (ONH)** for these measurements.

 Can you analyze the final coating in addition to the powder?
Absolutely. FILAB can perform **micrographic cross-sections** on your test coupons to verify porosity, thickness, and structure of the deposit according to your complementary specifications.
