White morundum F80 for titanium parts coating preparation

High-purity white morundum is an excellent grinding and sandblasting medium for surface preparation after casting formation and before spraying coating. On the research surface, 99% white morundum F80 is used for sandblasting and acid etching treatment of titanium parts. The surface roughness was about 3um, which was beneficial for the coating to adhere to the surface of titanium parts.

Pure titanium precision castings have advantages such as lightweight, high strength, heat and corrosion resistance, and good biocompatibility. Therefore, titanium castings, such as artificial joints and dental stents, are widely used in the medical industry. Titanium materials are generally produced by precision casting to the desired shape and then processed into titanium products. The surface reaction layer after titanium casting is the main factor affecting precision-cast titanium parts. Especially as materials for artificial joints or tooth roots, it is necessary to apply bioactive dopamine coatings on the surface of castings to increase the material’s corrosion resistance. It can improve cell compatibility. Meanwhile, it can promote early bone integration of artificial implants.

White morundum with an average particle size of 180um equals WA grit 80 # particle size sand. Welcome to contact Haixu Abrasive, a manufacturer of white corundum, for consultation.
