Reason to use one of the thermal coating can be as follows

For new designed parts, sprayed coatings offer a rewarding combination of features:

• To create high performance parts that would be difficult or costly to produce by other means
• To value engineer new or existing parts by spraying premium material coatings over lightweight or low cost substrates
• To design composite material parts that use the best qualities of the sprayed coating and the structure member
• To provide a surface property not otherwise available

For repair and rebuild worn machine parts, sprayed coatings save time and money, while increasing service life:

• Parts can be rebuilt faster and at less cost with sprayed coatings than by using welding, plating or sleeving
• When new parts have to be ordered, spray repair can save days of downtime; yet the cost can run as low as 10% of replacement cost
• Because a premium material can be used as the build-up coating, repaired parts will outwear new ones
• Parts can be so easily rebuilt so that spare parts inventories can be greatly reduced

for salvage of mis-machined parts or undersized castings:

• A coating material equivalent to the original material can be chosen to restore dimension
• It results in much lower cost than completely refabricating a new part.
