Four Major Technical Problems Restricting The Application Of Light Weapons

Heat treatment problems. Since iron-nickel-cobalt-molybdenum alloy (Ni18Co9Mo5) belongs to martensitic aging steel, it requires repeated practice in heat treatment temperature control, coupled with various hardness requirements, which makes heat treatment more difficult, and requires on-site technicians to repeatedly explore and formulate strict heat treatment specifications. Comprehensive mechanical properties. This is the most critical issue. The impact toughness, plasticity and fatigue resistance of powder metallurgy parts greatly affect the application of this technology in high-performance parts. It is necessary to accurately judge whether it can be used in part evaluation. It has high requirements for designers. Without sufficient experience, it is impossible to undertake the work of selecting materials for light weapon parts.

Surface treatment problems. Generally, the surface film of powder injection parts is incomplete and flowery after surface treatment. The phosphating film of nickel-based (Ni18Co9Mo5) parts is slow to form and has poor adhesion. Iron-based (Fe4Ni05Mo) parts are relatively better, but not ideal. The surface treatment technology of powder metallurgy parts has been conquered, but the application of QPQ and PIP technology still needs in-depth research.

Welding performance problems. Due to the high carbon content, the stress after welding is large. Stress relief tempering (480℃ insulation for 2h) is required after welding.

China's Professional Powder Metallurgy Research Institutions

In the 1980s, MIM technology was approved by Central South University, Beijing University of Science and Technology and the Iron and Steel Research Institute to enter the scientific research and development stage, and was included in the national "863" high-tech research plan. The earliest national research institution for powder metallurgy technology in my country is the National Key Laboratory of Powder Metallurgy built on the basis of Central South University of Technology (now Central South University). It was approved by the State Planning Commission in 1989 and became a national laboratory in 1995.

In the military industry, the scientific research institution that studies the application of powder metallurgy technology in military equipment is Shandong Non-metallic Materials Research Institute, also known as the 53rd Institute of Ordnance Industry Group. It focuses on the research and development of new military materials and new processes, and its application objects are mainly modern weapons and equipment. It is mainly engaged in the modification and application of advanced resin-based composite materials, stealth materials, high-performance engineering plastics, ablation and thermal protection materials, etc.
