Nitriding is the saturation of the surface of a component with nitrogen by thermochemical operations. Due to the penetration of nitrogen into the component, the results are obtained as follows:
\nIncreased abrasion resistance (high hardness)
\nMaintain the toughness of the base metal,
\nIncreased fatigue resistance,
\nIncrease chemical corrosion resistance,
\nReduces the possibility of cracks in the piece.<\/p>\n
Salt bath nitriding, gas nitriding, and plasma nitriding are different types of nitriding.
\nPlasma nitriding takes place in a vacuum chamber connected to a high voltage. In this system, there are cathode components and an anode vacuum chamber. by the application of voltage, the plasma is formed inside chamber. The gases inside the chamber (nitrogen, hydrogen, and argon) ionize, and the released ions bombard the surface of the part, so the part bacome warm, its surface clean, and nitrogen adsorp on the surface.<\/p>\n

The presence of carbon in the furnace atmosphere increases the thickness of the white layer. The nitrogen-carbonation process is usually used on steels that are weak in terms of alloying elements and do not have the possibility of forming a hard penetration layer. By performing the nitrogen-carbonation process in such steels, a thick and hard white layer is formed, resulting in an increase in the surface hardness of the part.<\/p>\n [\/vc_column_text][\/vc_column][\/vc_row][vc_row rtl_reverse=”yes” mobile_bg_img_hidden=”no” tablet_bg_img_hidden=”no” woodmart_parallax=”0″ woodmart_gradient_switch=”no” row_reverse_mobile=”0″ row_reverse_tablet=”0″ woodmart_disable_overflow=”0″ el_id=”Post-Oxidation”][vc_column]\t\t\n\t\t After the nitrogenation or nitrogen-carbonation process, a supplementary oxidation process can be performed in the chamber. The goal of the complementary oxidation process is to form a 2-3 \u03bcm thick magnetite layer (Fe3<\/sub>O4<\/sub>). This layer is black and increases the chemical corrosion resistance of the part.<\/p>\n [\/vc_column_text][\/vc_column_inner][vc_column_inner width=”1\/3″][vc_single_image image=”174″ img_size=”full” parallax_scroll=”no”][\/vc_column_inner][\/vc_row_inner][\/vc_column][\/vc_row][vc_row rtl_reverse=”yes” mobile_bg_img_hidden=”no” tablet_bg_img_hidden=”no” woodmart_parallax=”0″ woodmart_gradient_switch=”no” row_reverse_mobile=”0″ row_reverse_tablet=”0″ woodmart_disable_overflow=”0″ el_id=”Plasma-Nitriding-of-Titanium”][vc_column]\t\t\n\t\t Today, titanium has found many applications in industry due to its lightness, strength, and corrosion resistance, but weak wear resistance has led to limitations in its use. Titanium nitrogenation is one of the methods to increase the improvement of surface properties of titanium alloys. During nitrogenation, TiN and Ti2<\/sub>N phases are formed, which increases the wear resistance. Titanium nitrogenation is difficult due to the need for temperatures higher than the nitrogenation temperature of steel and requires special equipment and technical knowledge.<\/p>\n [\/vc_column_text][\/vc_column_inner][vc_column_inner width=”1\/3″][vc_images_carousel images=”171,203″ img_size=”full” onclick=”link_no” autoplay=”yes” hide_pagination_control=”yes” wrap=”yes”][\/vc_column_inner][\/vc_row_inner][\/vc_column][\/vc_row][vc_row][vc_column]\t\t\n\t\t Plasmapazhouh Pars Company is providing services in the following fields by 4 plasma nitrogen furnaces with different dimensions that have been built in the same complex: The existence of several furnaces with different dimensions in the set has created the following two advantages: [\/vc_column_text][\/vc_column_inner][\/vc_row_inner][\/vc_column][\/vc_row]<\/p>\n","protected":false},"excerpt":{"rendered":" [vc_row el_id=”Plasma-Nitriding” mobile_bg_img_hidden=”no” tablet_bg_img_hidden=”no” woodmart_parallax=”0″ woodmart_gradient_switch=”no” row_reverse_mobile=”0″ row_reverse_tablet=”0″ woodmart_disable_overflow=”0″][vc_column][vc_row_inner rtl_reverse=”yes” row_reverse_mobile=”0″ row_reverse_tablet=”0″][vc_column_inner width=”2\/3″][vc_column_text text_larger=”no”] Nitriding is the saturation of the<\/p>\n","protected":false},"author":1,"featured_media":0,"parent":0,"menu_order":0,"comment_status":"closed","ping_status":"closed","template":"","meta":{"footnotes":""},"yoast_head":"\n
