Electrochemical Corrosion Testing
MEE just added a new potentiostat/galvanostat instrument to our busy corrosion laboratory. The VersaSTAT 4 is an advanced and versatile instrument expanding on our electrochemical corrosion testing capabilities. Electrochemical corrosion experiments can provide a variety of data related to the pitting, crevice corrosion, and passivation behavior for specific sample/solution combinations. These data are useful in […]
Nanostructures Imaging
These images are of a selective area of AlGaN (aluminum gallium nitride) nanostructures on graphene. Images were captured using the Field Emission Scanning Electron Microscope, FESEM, at MEE in support of a project partnership between CrayoNano AS of Norway and Agnitron Technology of Eden Prairie, MN USA. The FESEM is an advanced microscope offering increased […]
Materials Science and Engineering
This week, MEE hosted 28 University of St Thomas Materials Science students in our laboratory. Staff gave tours of our metallography, corrosion and light microscopy labs and presented a brief introduction to scanning electron microscopy.
Medical Device and Manufacturing
Medical device development calls for innovation, precision and critical thinking – MEE matches your requirements with advanced materials characterization, analytical methods and experienced and informed materials strategies. Look for us in the exhibit hall of the upcoming MD&M event November 8-9 at the Minneapolis Convention Center. Materials Evaluation and Engineering staff will be there to […]
Materials Science Camp 2017
Last Friday we had thirty high school students at MEE as part of a week-long Materials Science Camp sponsored by the MN Chapter of ASM International. Under the direction of industry and education based “Materials Mentors”, students got some real world experience solving a materials failure analysis project. Three of our staff, Larry Hanke, Kurt Schenk and Neal Hanke, […]
Technical Paper Published
“Broad Beam Ion Milling for Microstructure Characterization,” a technical paper authored by MEE staff Larry Hanke, Kurt Schenk and Dieter Scholz, was recently published in the online version of Materials Performance and Characterization. An abstract of the article is available on the ASTM International digital library site. Ion beam milling is a unique method of sample preparation that complements and significantly extends […]
Improving the Laboratory Environment
This summer, MEE completed a retrofit of our office and laboratory space to LED lighting. We had been looking for ways to save energy in our facility so we had a lighting assessment done and learned we qualified for the Xcel energy rebate program for retrofits. Benefits of the project were noticed soon after the work was completed. Our energy bill […]
The Intern Experience at MEE
Interns, Reid Schur and Josh Polzin, were a welcome addition to our team this summer. Reid completed a project comparing the chemical vs mechanical test methods used in ASTM D3483, Standard Test Methods for Accumulated Deposition in a Steam Generator Tube. We will use the information from his work to help our customers decide on the best test method to use with their […]
Testing to Industry Standards
We added a new page to our website, Testing to Industry Standards. Select ASTM test methods we have experience with are listed. The list is by no means all inclusive. If you don’t see the test method you require, contact us. We will work with you to interpret test methods and identify those tests we […]
Testing to Industry Standard D2240
With the purchase of a new Rex Gauge Type M Durometer, MEE has expanded its service capabilities for testing to industry standard ASTM D2240, Standard Test Method for Rubber Property—Durometer Hardness The durometer is the international standard for the hardness measurement of rubber, plastic and other non-metallic materials. The Rex Type M durometer can be used when checking […]
