Page "Remanufacturing" Paragraph 26

# Remanufacturing by recoating of worn engine parts ; many engine parts, components are large and expensive and after a period of use become worn.

An example of such a part is the engine block, in particular the cylinder engine bores, which must withstand explosions during piston firing.

Instead of disposing of large engine blocks, remanufacturing has resulted in re-use of the parts by coating them with plasma transferred wire arc spraying ( PTWA ) Caterpillar known for manufacturing very large industrial trucks and machinery has started such remanufacturing programs of equipment parts using PTWA, resulting in a greener environment.

Remanufacturing by recoating of parts is also very popular in the aircraft field, the geothermal pipe field and the automotive engine field.
