Chemical Processes for Steel Alloys

Our Chemical and Electrochemical processes are Nadcap Accredited moreover they are recognized and qualified by the major Aerospace Industries.

M.P.S. has a new indipendent plant for the chemical and electrochemical treatments of steel alloys, both fully automated with software for setting and monitoring the working parameters such as temperature, pressure, voltage, current, etc.

Tanks dimensions are: 1000 mm x 600 mm x 1500 mm h.

This new plant includes the new Zink-Nickel plating and Passivation.

All the solutions in the vats are continuously monitored, analyzed and optimized by the laboratory through the identification and analysis of polluting agents, the solutions concentration, PH, contained of TDS, speed of attack for pickling and de-greasing vat, etc. All this data is collected and used for the statistical control of the processes.

Other than the maintenance and control of the plant, instruments, vat solutions, working paramenters and everything pertaining to chemical and electrochemical processes, M.P.S. strictly follows customer specification carring out a considerable number of distructive tests such as corrosion tests (salt spray fog test), tests of adhesion after the chromate conversion treatment and anodic oxidation of aluminum alloys, calculation of the weight of the anodic covering and all the other tests required by our customers.

All the personnel that work on the plants are experienced and continuously trained.
