In recent years, surface engineering technology has developed rapidly in China and has its unique position in government science and technology development plan. As an end user, the community of equipment maintenance has steadily focused on the latest progress of surface engineering technology and quickly introduces its achievements into equipment maintenance to improve the operational performance of weapon systems and supporting facilities. It was found during an investigation of maintenance techniques that surface engineering technology was widely used in military equipment maintenance and had made great impact for their effectiveness. Applications of surface engineering technology such as nano-surface, thermal spraying, bonding and coating, co-osmosis in maintaining and repairing airplanes, vessels, submarines, vehicles and artillery have greatly enhanced their capabilities to resist wear and tear, erosion and fatigue and dramatically improved their operational efficiency and effectiveness. Surface engineering technology has made significant contributions to maintain operational readiness of equipment and weapon systems which, in turn, has generated huge martial and economical profits.

China is facing a severe situation of energy resources. High oil dependency is seriously threatening our economy’s fast and stable development. The US has successfully achieved the commercial development of shale gas, which has decreased its oil dependency, and also contributed to its natural gas geology and petroleum engineering technology development. Both Chinese and U.S. geological experts predict that China has similar quantities of shale gas reserves as founded in the United States. This paper aims to clarify that producing shale gas resources has economic significance of energy security and environment protection, and scientific significance of promoting the further development of natural gas geology and petroleum engineering subjects.

The Japanese Ministry of International Trade and Industry (MITI) has started two nine-year national R&D projects for small-capacity ceramic gas turbines (CGTs) from 1988, following several preliminary investigations of the technical aspects and of the social impacts of CGTs. Planned 300kW industrial ceramic gas turbines are to be used for co-generation and mobile power generation. The goals are 42% and higher for the thermal efficiency at the turbine inlet temperature of 1350°C, and the emission from the exhaust gas should meet the regulatory values. Also ceramic components have the goals of 400MPa for the minimum flexure strength at 1500°C, and 15 MPam1/2 for the fracture toughness. New Energy and Industrial Technology Development Organization (NEDO) is the main contractor, and three groups of private industries are the subcontractors for 300kW industrial CGT project. Three national research institutes are involved in the projects to conduct supportive research of ceramic materials and engine components as well as to carry out assessment of the materials and engine systems developed by the private industries. The development of 100kW CGT for automotive use was also recommended in the above stated investigations and a two-year preliminary study started in 1988. The full-scale 100kW automotive CGT R&D project is scheduled to start in 1990 after the preliminary study. Japan Automobile Research Institute, Inc. (JARI) is the main contractor for 100kW automotive CGT project with the cooperation of three automobile companies.

Within the scope of this work, a new surface engineering technology named laser implantation has been investigated, in order to improve the tribological performance of hot stamping tools. This technique is based on manufacturing highly wear-resistant, separated, and elevated microfeatures by embedding hard ceramic particles into the tool surface via pulsed laser radiation. Hence, the topography and material properties of the tool are modified, which influences the thermal and tribological interactions at the blank-die interface. To verify these assumptions and to clarify the cause–effect relations, different titanium-based particles (TiB2, TiC, TiN) were laser-implanted and subsequently analyzed regarding to their geometrical shape and mechanical properties. Afterwards, quenching tests as well as tribological experiments were carried out by using titanium-diboride as the most promising implantation material for reducing the tribological load due to high hardness value of the generated implants. Compared to conventional tooling systems, the modified tool surfaces revealed a significantly higher wear resistance as well as reduced friction forces while offering the possibility to adjust the thermal interactions at the blank-die interface. Based on these results, a tailored tool surface modification can be pursued in future research work, in order to enhance the effectiveness of the hot stamping technology.

In September 2008, Origin completed a $9.6 billion transaction with ConocoPhillips to form Australia Pacific LNG (APLNG)—a fifty-fifty coal seam gas to liquified natural gas joint venture. As the upstream operator, Origin is planning to ramp up production to more than five times present production levels. In a two-year period, Origin tripled Queensland CSG production volumes to 300 Tj per day. This expansion was based on existing business systems and processes and it was recognised that additional capability would be required to further ramp up production and associated activities. A project was commissioned to build operational capability and capacity—processes, systems, organisation design and people—to efficiently drill the required number of production wells. This priority project addressed a business objective to step up the drilling of CSG production wells from approximately 60 to 350–400 per annum. The transformational solution comprised three key components: business process re-engineering, technology development, and organisational re-design. The solution included the definition, documentation and transformation of business processes—this ensured consistent, repeatable and scalable processes capable of drilling of 350–400 wells per annum. The processes are now enabled by resource scheduling and document management systems that are fully integrated. The resultant well delivery system is managed by a team that provides the business with decision making information regarding the resource use required to support the delivery of the APLNG commitments. Given the transformational nature of the solution, the delivery of all three components was under-pinned with change management impact assessments, education, communications and deployment. The total solution was deployed in August 2010.
