Study of Mechanical Properties in the Interface Applied in Thick Coatings Obtained by Thermal Spraying

Abstract:

This work appears as an experimental attempt to verify the validity of thetheoretical model used to interface ratio proposed by Chicot and Lesage. For this, wepresent a study on the mechanical properties of interface from the instrumentedpenetration tests. One of the important points of the study is related to the characteristicsof materials with micro deformations and influence of defects on the mechanicalproperties. Discussions are developed concerning the intrinsic properties, particularlythe behavior of the modulus of elasticity for different situations in which the materialsare. Were used for development work, samples taken from sucker rods, which are usedin oil production equipment. These rods were coated with two types of materials, thebasis of a NiCr alloy and the other with Al, both obtained by thermal spray process (arcspray). With the use of instrumented penetration testing was carried out indentations inthe coatings, substrate and interface of each sample. With these results, the model wasapplied and theoretical interfacial later tried to verify its validity.
