A New Method for Evaluating the Bond Strength of Plasma-Sprayed NiCrBSi Coatings
نویسندگان
چکیده
The bond strength is a critical consideration for the plasma-sprayed NiCrBSi coatings. However, conventional methods testing of coatings always cost time and money. If there simple method that could predict prepared without destroying coatings, it would be significantly beneficial industrial applications. In this work, new was proposed based on total areas interfacial pores coating by plasma spraying technology as-sprayed subsequently remelted arc using powers 20 kW, 25 30 respectively. microstructures, size distributions pores, hardness, all samples were investigated. After remelting, number area decrease with increasing remelting power. Correspondingly, hardness increase power basically has linear relationship pores. built may used to

متن کاملA new method for shear bond strength measurement
Modeling the tensile strength of paper has been a topic of interest over the last few decades. Fibre properties and fibre network properties are the two main sets of inputs required for any such analytical model. Out of these, the most difficult quantity to measure is the “Fibre-Fibre Shear Bond Strength”. No reliable method exists for the measurement of this quantity. This paper reports a simp...
