ISS Science for Everyone

Science Objectives for Everyone
The COOLCOP experiment focuses on Copper-Cobalt (Cu-Co) samples, and the determination of surface tension and interfacial tension of those immiscible alloys. The droplet growths are studied on Earth post-flight.

Experiment Description

Research Overview

  • Most of the metals used by humans are not pure, but an alloy of different materials. By combining different metals, materials can be concocted that offer the best of their component parts. The stainless steel used in most knives and forks is actually an alloy of one part chromium to 10 parts steel, that renders the alloy more resistant to corrosion.
  • Super-alloys using the latest space technology are now being used in smartphones and jet engines, but ESA is always looking for better, lighter, stronger, and cheaper materials. Some metals and materials do not mix easily.
  • COOLCOP investigates cobalt and copper, two metals that do not mix easily on Earth. By observing the process in the Electromagnetic Levitator and looking specifically at surface tension, scientists and ESA's industrial partners hope to improve metal casting processes on Earth.

Applications

Space Applications
Industry partners to the projects are seeking to optimize ground processes, and have a direct interest in the knowledge that is gained from the experiments. This can, in turn, find its way into the development of new light-weight, high-performance structural materials for space applications.

Earth Applications
Investigations carried out with the Electro-Magnetic Levitator (EML) provide both reference data on thermophysical properties and microstructure formation for the same metallic alloy samples. (The microstructure in an alloy influences its characteristic properties such as strength, flexibility and resistance to fatigue). This information is of importance for feeding accurate data into current numerical models on one side, and also testing these models aiming to predict the solidification profile and related microstructure formation in the alloy samples. This concerns structural steels, magnetic materials, intermetallic materials, glass forming metallic alloys etc.

Operations

Operational Requirements and Protocols
After container installation by crew, all activities are fully commanded by ground. Sample processing is executed during crew sleep, with continuous Ku and S band coverage so that micro-g-level and vibrations are known. One run per sample, with several melting cycles. Exact number of melting cycles for this experiment is still to be determined.
Copper-Cobalt (Cu-Co) Samples to be returned:

  1. Cu75Co25
  2. Cu89Co11
