The present research develops HAP coating on titanium alloys and concerns is given in studying the effect of carbon nano tube (CNT) intermediate layer on HAP coated titanium alloy. From SEM characterization, it can be observed that both of HAP coated samples with and without CNT intermediate layer have porous nodular structure, a characteristic of thermal spray coating without any micro-crack. However finer and more irregular structure observed on the sample with CNT intermediate layer, which is confirmed from XRD characterization, that lower degree of crystallinities occurs on sample with CNT intermediate layer. After the coating, both of the samples were post annealed at 600 and 700°C for one hour. It was observed that micro-crack observed on the sample without CNT intermediate layer after post annealed at 700°C, while the rest of both samples observed without micro-crack.[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Author keywords” size=”size-sm” text_align=”text-left”][vc_column_text]Coated titanium,Effect of carbons,HAp coatings,Hydroxyapatite (HAp),Intermediate layers,Irregular structures,Nodular structures,Thermal spray coatings[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Indexed keywords” size=”size-sm” text_align=”text-left”][vc_column_text]CNT Intermediate layer,HAP coating,Titanium alloy[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Funding details” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”DOI” size=”size-sm” text_align=”text-left”][vc_column_text]https://doi.org/10.4028/www.scientific.net/AMM.660.937[/vc_column_text][/vc_column_inner][vc_column_inner width=”1/4″][vc_column_text]Widget Plumx[/vc_column_text][/vc_column_inner][/vc_row_inner][/vc_column][/vc_row][vc_row][vc_column][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][/vc_column][/vc_row]
