CHANGE THE STATUS OF PLASMA JET SURFACE TO METAL BENCHMARKS (TO INCREASE ADHERENCE, ROUGHNESS) ASSEMBLED BY GLUING

Gábor PINTYE, Gheorghe ACHIMAŞ, Gavril PATAI

Abstract


Plasma processing technology was first used in the World War II in the US aviation factories. In the early 60s, engineers made a new discovery, the increase of the jet speed by narrowing the plasma nozzle. Due to the rapid development of science engineering, the plasma technology is used today in various fields: automobile manufacturing, aerospace, automotive industry, medicine, biology, etc. . . In processing of plasma jet, there are two patterns: at low pressure and at atmospheric pressure. Research carried out at atmospheric pressure have their advantages: size bodies  is not limited, surfaces can be modified without altering the volume properties, low temperature can avoid destroying the materials. Surface modification of plasma materials refers to changing the properties of the surface, creating surfaces with unique properties and characteristics thus improving the mechanical properties. Modification of surfaces ,,texture’’ permit infiltration of adhesive thus improving mechanical resistance, that will be verified in some tests:tensil strength, shear strength, resistance to separation and resilience.

 Keywords: plasma arc, plasma jet, superficial surface, roughness, penetration, mechanical strength.
