How I can achieve 7A/dm2 current density in the electroplating process? My substrate size is Φ 0.10x0.50x38x3.00 mm?

Electrodeposition process of the Zinc-Nickel coatings

Please find the EDS report attached here.

Please comment soon.

Please suggest methods to calculate bar value from EDS analysis.

Hello everyone,

I am actually performing a corrosion rate analysis for a sample of aluminium that is electroplated with nickel. I am using Linear Polarisation using the Palmsens EmStat 4s potentiostat.

However, to find the yearly corrosion rate, I need to add data regarding the equivalent weight and density of the metal sample that I am testing.

For pure aluminium, the equivalent weight is 9, and density would be 2.7 g/cm3; however, what would I consider if the aluminium has an electroplated coating of nickel? Considering nickel's equivalent weight and density would be inaccurate, right?

Please let me know what values would be suitable.

Regards.

Dear respected members

Thanks in advance to provide valuable comments/suggestions.

I fixed 3t3 fibroblasts from 15cm plates today. They were 100% confluent and I was therefore very surprised to count only 4.4x10^6 cells/plate. I would like to know what the norm is. Thanks a lot!

The shape of the earth electrode may vary from conductive rod, conductive plate, metal water pipe or any other conductor with low resistance. Earth electrodes are made of copper, galvanised iron, cast iron etc.

I elaborated an Ni-W coating under pulsed currents. For corrosion tests, I studied the evolution of the phase angle diagram by EIS (Electrochemical Impedance Spectroscopy). The porosity of films was calculated using image analysis. I'd like to know if there is a mathematical relationship between porosity of the coating and the phase angle vs. frequency diagram.

I have a 3D model of the distal femur built in Mimics using CT Scans. I have also assigned the material properties using the empirical formulae from certain published papers. My question is, is there a way to save the values of Density and Modulus thus derived, in a seperate file in the Node/Element - Density - Modulus format? (istead of the properties being contained in the mimics model file itself)
