In 1989, Chocola helped form coatings
manufacturer REFCOTEC, Orrville, Ohio, before retiring in 2004.
Thus the directional electro-thermal wire explosion spraying technique (DEWES) was developed, which enabled to form coatings
on internal and external cylindrical, plane or profiled surfaces.
The colonies often form coatings
, known as biofilms, which protect them from antiseptics, disinfectants, and antibiotics.
powders from two batches having different size fractions have been vacuum plasma sprayed to form coatings
using different sets of spray parameters.
Modifications to the bath chemistry are made to suppress gas evolution, accelerate coating formation, or form coatings
on Cu-rich alloys.
