Title: Innovations by Inventor Hans Gotta

Introduction

Hans Gotta is a notable inventor based in Weiden, Germany. He has made significant contributions to the field of metal surface treatment, holding two patents that showcase his innovative approaches. His work focuses on improving methods for preparing metal surfaces prior to phosphatization, which is crucial in various industrial applications.

Latest Patents

One of Hans Gotta's latest patents is a method of treating metal surfaces prior to phosphatization. This invention is directed to an improved method for cleaning, scouring, and activating metal surfaces. It involves contacting metal surfaces with an aqueous solution containing primary and/or secondary alkali metal or ammonium salts of orthophosphates, along with conventional metal cleaning components. The solution has a pH value ranging from about 6.3 to 8.2, which is lower than that of solutions of the corresponding secondary orthophosphates alone at the same concentration. Additionally, the solution may contain condensed phosphates to soften the water hardness used.

Another significant patent by Gotta is the process for the production of sprayed phosphate coats on iron and steel. This process involves applying a phosphate coating to a ferric surface by spraying an aqueous acidic solution at a pH of 4.3 to 6.5. The solution contains an orthophosphate salt of a cation selected from alkali metals and ammonium, along with oxidizing or reducing agent accelerators. The improvement in this process includes adding a short-chain alkylolamine and a non-ionic surface-active wetting agent to enhance the coating application.
