Ti Content

In order to increase the service life for piston rings, the (Cr ,Ti) N composite coatings have been successfully synthesized on 65Mn steel substrates by using arc ion plating technology. The influences of Ti content on the deposition velocity, phase structure , surface morphology and hardness of the composite films were investigated. The results showed that the surface roughness will reduce after addition of Ti element. And the hardness, residual stress of CrN films will increase after addition of Ti element. The preferential growth orientation of the composite film changes from CrN (111) to CrN (220). With increasing Ti content, the phase structure of CrTiN films will change from CrN type to TiN type. When the Ti atomic number was 0.62, the hardness of CrTiN composite films reaches the maximum, about 35GPa. Wear test indicate that the fiction of CrTiN films are lower and the wear volume are less than CrN films. The CrTiN composite films performs better than binary CrN films in teams of hardness and wear resistance at high temperature.

The Chinese government attempts to use market-oriented measures, such as energy performance contracts (EPCs) rather than mere policy mandates, to encourage manufacturers to voluntarily adopt green technologies. However, the low use rate of EPCs in existing diffusion projects calls for an in-depth examination. This article, therefore, aims to investigate the adoption risks that thwart key stakeholders, as well as the stakeholders' trust that may mitigate the aforementioned risks, through a case study of the national-level diffusion project. Using network analysis, this study identifies four critical risks that are associated to key stakeholders, that is, information asymmetry, funding support, payback period savings potential, and technical competences. Furthermore, it discloses the linkages between stakeholders' trust perceptions and the aforementioned risks. This outcome gives us new insights about what can be improved to better promote EPCs in diffusion projects on a national scale.

In the last 20 years, with the liberalization of the economy, and the trend of industrial globalization, people have gradually paid more attention to environmental protection. With the tremendous advances in information technology, enterprises facing such a severe impact on the business operations, business administrative models must be innovative and adaptable in order to survive and flourish. The paper industry is not only a highly polluting industry, but in the case of long-term overcapacity, the price of paper products is often suppressed, which lowers profitability. The purpose of this study, which is based on the production data of a paper company, is to pose a mathematical programming decision model which integrates green manufacturing technologies, activity-based costing (ABC), and the theory of constraint (TOC); this model should assist in preparing the best production plans, and achieve the optimal profitable product mix. In addition, this study also proposes that the most popular related technologies developed by Industry 4.0 be applied to production control in recent years in order to enhance production efficiency and quality. The findings of this study should contribute to the improvement of the competitiveness of the paper industry, and provide insights into the value of an integrated mathematical programming model applied for product-mix decision. At the same time, we have also applied the related technologies developed by Industry 4.0 to machine maintenance and quality control in manufacturing workshops. With its tremendous benefits, we can actively arouse the industry’s understanding of, and attention to, Industry 4.0, thereby increasing the interest in industrial 4.0-related technology investments.

As a sustainable model of modern manufacturing industry, green manufacturing is one of the essential solutions of the manufacturing environment pollution problems. Green cutting technology is the base and key of green manufacturing and will be the inevitable trend of cutting technology. High speed machining technology is a kind of the advanced manufacturing technologies which have superiorities as low cost, high efficiency, good processing quality and are suitable for machining thin walled workpieces and difficult-to-cut materials, and the relative problem has attracted scholars' attention from all over the world. From the perspective of green manufacturing, research results of high speed machining hardened steels are reviewed, including cutting force, cutting temperature, selection and optimization of processing parameters and machining quality, and conclude that high speed cutting is one of the key technologies in implementing green manufacturing and cleaner production. Finally, its future works of the research are discussed.
