This utility model provides a wear-resistant and high-toughness composite titanium-based cermet cutting tool, relating to the field of metal cutting technology. It includes a tool head assembly, which comprises a titanium-based cermet base, a transition layer, and a composite wear-resistant coating. The composite wear-resistant coating is deposited on the surface of the tool head assembly by magnetron sputtering. The transition layer covers the outer side of the composite wear-resistant coating. The tool head assembly consists of a titanium-based cermet base, a transition layer, and a composite wear-resistant coating. The 8-12μm thick composite wear-resistant coating is applied to the surface by magnetron sputtering, effectively resisting wear and significantly extending the tool head's service life. The transition layer covers the outer side, enhancing the bonding force between the coating and the base, uniformly dispersing stress, and improving overall stability. The cutting edge on the outer side of the titanium-based cermet base has a reasonable angle design for efficient cutting. A locking groove below the base forms a tool clamping rod, providing a secure connection and facilitating installation and disassembly. This allows the tool head assembly to operate accurately and efficiently in various cutting operations, reducing maintenance costs and improving processing efficiency and product quality.

This utility model relates to the field of power facility technology, and in particular to a PE and PVC blended structural wall pipe. The technical solution includes: a pipe body and an overhead ring. The pipe body is composed of a non-toxic bitter layer, a hardened layer, a composite layer, a core, and an antistatic coating. The non-toxic bitter layer, hardened layer, composite layer, core, and antistatic coating are arranged sequentially from the outside to the inside. The outer ring surface of the overhead ring is equidistantly fixed with ball seats, and rolling balls are rotatably mounted on the ball seats, rolling in contact with the inner wall of the pipe body. This utility model, through the synergistic design of a multi-layered composite protective pipe body and a ball-supported overhead ring, achieves an integrated cable protection structure that is rodent-proof, abrasion-proof, antistatic, and has high-strength compressive strength, significantly improving the safety and durability of cable laying.
