Titania Thermal Spray Powders

Introduction

A titania coating is a smooth and dense coating with a specific ductility. The combination with TiO2 is common and has been discussed. Other combinations (45-60% Cr2O3) are used as well.

Properties

Average abrasion resistance
Soluble in bases and H2SO4 but resistant in many other media
Electrical conductive.

Applications

Mandrels in dry battery production
Scratch resistant design coatings
