For plating applicators, paraffin residue can cause poor adhesion, delayed blistering or other poor-quality performance of the plated deposit, including poor corrosion resistance. Coventya director of business development Greg Terrell explains how to remove paraffin-based lubricants prior to plating.
LumiShield recently conducted a demonstration of its Lumidize aluminum electroplating process at the 100-gallon scale, signifying the technology’s readiness for production-scale plating.
Global aerospace manufacturing company Polamer Precision, has worked with SIFCO ASC to bring a selective plating process in-house for improved output, lead time and quality control.
Replacing old SCR rectifiers may help lower electrical costs, but choosing between modern SCR and SMPS rectifiers requires some careful consideration.
SIFCO ASC engineers Dr. Ani Zhecheva Brain and Danijela Milosevic-Popovich discuss the challenges of being a woman in a STEM related field, reflect on the achievements of women in engineering and talk about opportunities for women and girls interested in STEM.
The effect of anodizing voltage on the adhesion of nickel electrodeposited on anodized aluminum is related to the morphology of the anodic film. In general, adhesion is a linear function of the applied anodizing voltage. New data on the initial stages of pore formation during anodizing indicate that: (1) that the growth mechanism during the initial stage (< 10 sec) differs from that during subsequent growth, (2) there is no metallic bonding and (3) electrodeposited nickel coatings typically fill the entire pore.
