摘要
摘要 研究了镍基粉末及其等离子涂层中氧和氮的含量。根据镍基喷涂材料与氧的相互作用机理将其分为四组:(i) 镍;(ii) 与铬合金化的合金;(iii) 与铝额外合金化的合金;(iv) 与铬、C、B 和 Si 进行更复杂合金化的合金,这些合金与氧有积极的相互作用,包括形成气态氧化物。使用 20% Cr(以下以重量百分比表示)合金可将涂层中的氧含量降低 35%,使用 17% Cr-10% Al 合金可将氧含量降低 57%,而使用 13.5% Cr-2.7% Si-1.65% B-0.36% C 的更复杂合金可将氧含量降低 92%。提高等离子喷射功率可将镍-20% 铬镀层中的氧含量从 0.55% 提高到 1.6%。提高等离子喷射功率并在喷涂前预热基体,可使使用等离子喷嘴的 Ni-17%Cr-10%Al-1%Y 和 Ni-15%Cr-4%Fe-0.8%C-4.1%Si-3.1%B 涂层中的氧含量有限增加,这消除了等离子喷射的热效应,并限制了基体上涂层形成区的大气氧供应。使用喷嘴喷涂的 Ni-17% Cr-10% Al-1% Y 涂层含有 0.48% 的 O 和 0.14% 的 N,而不使用喷嘴喷涂时则含有 2.31% 的 O 和 0.37% 的 N。镍、镍-20% 铬和镍-40% 铬涂层中氧和氮含量的增加,以及这些涂层中液态硬化结构的形成,决定了其显微硬度比粉末硬度增加了 1.6-1.9 倍。
The Study of the Content of Oxygen and Nitrogen in Nickel-Based Plasma Coatings
Abstract
The content of oxygen and nitrogen in nickel-based powders and plasma coatings made of them has been studied. The Ni-based sprayed materials were divided into four groups according to the mechanism of their interaction with oxygen: (i) Ni; (ii) alloys alloyed with Cr; (iii) alloys additionally alloyed with Al; and (iv) alloys with more complex alloying with Cr, C, B, and Si, which actively interact with oxygen, including the formation of gaseous oxides. Alloying with 20% Cr (hereinafter in wt %) reduces the oxygen content in the coating by 35%, alloying with 17% Cr–10% Al reduces the oxygen content by 57%, and more complex alloying with 13.5% Cr–2.7% Si–1.65% B–0.36% C reduces the oxygen content by 92%. Increasing the plasma jet power increases the oxygen content in the Ni–20% Cr coating from 0.55 to 1.6%. Increasing the plasma jet power and preheating a substrate before spraying results in a limited increase in the oxygen content in the Ni–17% Cr–10% Al–1% Y and Ni–15% Cr–4% Fe–0.8% C–4.1% Si–3.1% B coatings using a plasma nozzle, which eliminates the thermal effects of the plasma jet and restricts the supply of atmospheric oxygen in the formation zone of the coating on the substrate. The Ni–17% Cr–10% Al–1% Y coating sprayed with the nozzle contains 0.48% O and 0.14% N instead of 2.31% O and 0.37% N when sprayed without the nozzle. An increase in the content of oxygen and nitrogen in the Ni, Ni–20% Cr, and Ni–40% Cr coatings together with the formation of a liquid-hardened structure in these coatings determines an increase in microhardness relative to that of the powder by 1.6–1.9 times.
期刊介绍:
Inorganic Materials: Applied Research contains translations of research articles devoted to applied aspects of inorganic materials. Best articles are selected from four Russian periodicals: Materialovedenie, Perspektivnye Materialy, Fizika i Khimiya Obrabotki Materialov, and Voprosy Materialovedeniya and translated into English. The journal reports recent achievements in materials science: physical and chemical bases of materials science; effects of synergism in composite materials; computer simulations; creation of new materials (including carbon-based materials and ceramics, semiconductors, superconductors, composite materials, polymers, materials for nuclear engineering, materials for aircraft and space engineering, materials for quantum electronics, materials for electronics and optoelectronics, materials for nuclear and thermonuclear power engineering, radiation-hardened materials, materials for use in medicine, etc.); analytical techniques; structure–property relationships; nanostructures and nanotechnologies; advanced technologies; use of hydrogen in structural materials; and economic and environmental issues. The journal also considers engineering issues of materials processing with plasma, high-gradient crystallization, laser technology, and ultrasonic technology. Currently the journal does not accept direct submissions, but submissions to one of the source journals is possible.
