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).


The materials Metco 4016A and Metco 4016B of this material family differ primarily in their particle size distribution and are all manufactured via HDH.

Handling recommendations

Store in the original container in a dry location; Open containers should be stored in a drying oven below 38°C (100 °F) to prevent moisture pickup; Tumble contents prior to use to prevent material segregation.

Other

Metco 4016A and Metco 4016B are sponge products which are less dense and exhibit porosity in the powder particles. These types of powders can not only be used for thermal spray coatings, but can also be used to form parts using HIP (Hot Isostatic Pressing).
