Description

Oerlikon Metco’s titanium and titanium alloy powders produce coatings having a range of characteristics not found in any other thermal spray powder materials. The coatings are light in weight with high strength-to-weight ratio and resistant to most corrosives. Titanium readily combines with other metals to form useful alloys. Owing to these suitable mechanochemical properties, pure titanium and titanium alloy powders can be employed in a number of applications via chemical, powder metallurgy and thermal spray processes.


Thermal spray coatings of titanium-based materials are commonly used in medical applications where biologic compatibility is required. Additionally, these coatings may also be used as a potential bond coat for hydroxylapatite coatings that are often used as a top-coat on biomedical implants. Titanium powders may also be used to produce dense, corrosion resistant coatings. Titanium powders have strong affinity and reactivity with oxygen, hydrogen and nitrogen at high temperatures. Most of the thermal spray coatings from these powders are produced under controlled atmosphere conditions (low pressure or soft vacuum).

Other

Grade 4 titanium powders are recommended for use in biomedical applications. For some biomedical applications, layers of both the fine and the coarse powders may be applied serving different functions. Atomized products are comprised of fully dense powder particles that are free-flowing and highly spreadable. These products will also give the best results for processes that require a high packing density to achieve high loading, such as MIM.
