AI Technical Summary

Benefits of technology

This patented technology describes how we can create better materials for use in applications where they will be subjected to severe conditions such as shocks or vibrational loads. These improvements include increased strength without losing their effectiveness due to excessive amounts of metal left over after processing by thermal treatments like sintering (hot) oxidation). Additionally, this new method allows for controlled formation of specific types of carbons called nitrides that enhance its properties while reducing cost compared to traditional methods.

Problems solved by technology

This patented technical problem addressed in this patents relates to improving the durable nature of conventional welded steel balls while maintaining their ability to prevent damage from small objects such as stones during use at extreme temperatures.

Abstract

The invention discloses an impact-resistant high-hardness wear-resistant ball which comprises the following raw materials in parts by weight: 100 parts of waste steel, 18-25 parts of ferrochromium, 1-1.5 parts of ferromolybdenum, 1-1.3 parts of ferrovanadium, 0.1-0.3 part of ferromanganese, 0.2-0.6 part of ferrosilicon and 2-5 parts of zinc. In a preparation process of the impact-resistant high-hardness wear-resistant ball, the surface of the wear-resistant ball is modified by adopting plasma cladding and electric spark deposition technologies; plasma cladding process parameters comprise non-transferred arc voltage, non-transferred arc current, transferred arc voltage, transferred arc current, ionized gas stream, powder feeding gas flow, protection gas flow, cladding speed, welding gun swing range and spraying distance; the electric spark deposition process parameters comprise argon gas flow, deposition voltage, deposition frequency, deposition power, deposition time and rotary deposition gun speed. The wear-resistant ball is excellent in impact resistance, corrosion resistance, hardness, heat resistance and wear resistance.
