“…During the conventional plasma-nitrided (CPN) treatment where the workpiece serves as the cathode of the discharge system, there will be some problems that are difficult to solve, such as the edge effect [12]. The active screen plasma nitriding (ASPN) technology thus came into use [5,[13][14][15][16][17][18][19]. The gas in the furnace is ionized, the surface of metal screen is heated after ion bombardment, and the workpiece reaches nitrided temperature through radiation.…”

Plasma nitriding is a widely used technology to enhance the surface performance and extend the service life of alloy parts. The current research mainly focuses on the influences of time, temperature, gas type and pressure parameters on nitriding behavior, while fewer studies have been conducted on the electric potential. This paper mainly reports the effect of the electric potential on nitriding behavior. Test conditions were set using cathodic, anodic and floating potentials in a plasma nitriding furnace. 2Cr13 stainless steel was nitrided at 450°C for 5 h in an NH 3 atmosphere. The experimental results show that the nitriding treatment can be well performed under the different electric potentials, but differences exist in microstructures, morphologies and performance results of the modified layers. The thickness and hardness values of the nitrided layer are ranked as follows: cathodic [ anodic [ floating potential. The anodic nitrided surface has an obvious particle deposition layer composed of nitrides and oxides. Electrochemical and tribological experiments show that the corrosion resistance and wear resistance were significantly improved after a nitriding treatment using the three electric potentials. Moreover, the floating nitriding treatment resulted in the best tribological performance and corrosion resistance.

“…The mechanism of CCPD is based on cathodic cage sputtering and re-deposition of the cage material on the substrate, which suggests that the thin film-forming elements may be deposited in accordance with the cage material. This technique has been used previously for the deposition of several materials, including copper, silver, aluminum, niobium, and titanium, depending on the required results [58].…”

The cathodic cage plasma deposition (CCPD) is an advanced technique recently developed from an active screen plasma nitriding system, which has been used for thin film deposition such as titanium nitride and titanium dioxide (TiO 2). These coatings can improve the physical, mechanical, and optical properties of numerous materials, and such coatings can be developed by several techniques. Unfortunately, the conventional deposition techniques exhibit certain drawbacks, including high cost, the complexity of the operation, very low pressure, and high processing temperature; as a result, CCPD is an advantageous technique. In this review, brief information on the deposition of titanium nitride and oxide coatings on steel alloys, titanium, glass, and silicon substrates, and the effect of control parameters on deposition efficiency is provided. The effectiveness of this system for the synthesis of thin films on various substrates, including insulators and conductors, is also summarized. The recent developments and applications of CCPD for titanium-based coatings are described in detail.

“…A nitretação a plasma em gaiola catódica, evolução da técnica de nitretação a plasma convencional, é um método que vem sendo utilizado para o aprimoramento de características superficiais de vários materiais [11]. Os principais benefícios consistem em minimizar as limitações ou defeitos provenientes da nitretação convencional como efeito de borda, abertura de arcos e efeito de cátodo oco em amostras com geometria complexa [12,13].…”

RESUMO A crescente necessidade de aumentar a produtividade do setor industrial, impulsiona o desenvolvimento de novos aços e novos tratamentos que possam melhorar o desempenho e a vida útil de ferramentas de corte, conformação e estampagem. Tratamentos de superfície assistidos por plasma destacam-se nesse contexto. Trabalhos anteriores têm demonstrado que esses revestimentos são eficientes no aumento da dureza, na resistência ao desgaste e na resistência a corrosão de diversos tipos de aços. Nesse sentido, amostras e ferramentas de aços AISI M2 e D2 termicamente tratadas foram submetidas aos processos de nitretação a plasma convencional, em gaiola catódica e tratamento duplex com o objetivo de avaliar o efeito desses tratamentos em ferramentas de conformação buscando a viabilidade da aplicação do método no setor industrial com a redução do custo de fabricação na conformação e estampagem de pregos. Ensaios de microdureza Vickers, análise por MEV e Difração de Raios-X (DRX) possibilitaram identificar propriedades mecânicas, camada de compostos e as fases presentes, respectivamente. O desempenho das ferramentas baseou-se na quantidade de pregos produzida em kg. O custo produtivo foi determinado em função da produtividade, do preço de aquisição da ferramenta e do preço da nitretação. O uso da nitretação a plasma se mostrou viável para os dois aços, destacando-se o fato de que as ferramentas de aço D2 nitretadas a 480ºC por 3 horas, obtiveram os maiores ganhos de produtividade em relação a ferramenta não nitretada. A aplicação da nitretação convencional na ferramenta de aço M2 a 480ºC por 4 horas possibilitou a redução de seu custo em 26% e redução de 3,5% sobre o custo total de produção de pregos, obtendo o melhor custo-benefício.
