“…Furthermore, it is also impossible for any experimental technique to acquire a complete mapping of the heat distribution in a general welded structure. Computational simulation thus plays an indispensable role in the integrity analysis of such welded structures [13][14][15][16][17].…”

The aim of this paper is to at first evaluate the influence of three key parameters including weld current, weld time and electrode force on nugget diameter and tensile strength in resistance projection welding. Then, a 2-D axis-symmetric finite element model is developed to simulate the projection welding and predict the nugget diameter. Finally, the FEM results are compared to experimental data to verify the simulation model and simulated results. In the finite element model, the temperature-dependent material properties were taken into account.

“…The useful lifetime of Zn and Zn alloy electrodeposits can be further increased by the formation of a passive film on their surface [16][17][18][19][20][21]. Chromate and phosphate films are common additional surface treatments used for various applications in different industrial fields [22][23][24][25][26][27][28][29][30].…”

The aim of this study is to investigate the effect of nitrate and nitrite on the weight, morphology and electrochemical properties of phosphated Zn-%12Ni electrodeposit coatings.In order to investigate phase structure and surface morphology of samples, X-ray diffraction and scanning electron microscopy were employed. In order to measure corrosion resistance behavior of the coats, Potentiostat/Galvanostat test was used. The results showed that nitrite accelerator reduces coating weight and surface porosity simultaneously obtaining by phosphating solution. Furthermore, coatings which were obtained by the nitrite accelerator had a higher corrosion resistance than that of the nitrate accelerator.
