Scale Patterned Wear Resistant Coating for Plow Blades
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Plowing systems, such as snowplowing vehicles, face wear and damage issues due to contact with hard and rough road surfaces, leading to accelerated wear of components like plow blades and shoes, exacerbated by friction and vibration.
Innovation Solution
A wear-resistant coating with a scale pattern is applied to the wear surfaces of plowing system components, comprising hardened materials like steel, carbide, and ceramics, arranged in staggered rows to reduce friction and distribute weight evenly, thereby reducing wear and damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If sacrificial parts (shoes) are used to support the plow blade weight, then damage to expensive components is reduced, but friction with the road surface generates heat that accelerates wear of the shoes
Solution Approach 1:
The patent applies a wear-resistant coating with modified surface properties (hardness, friction characteristics) to the shoes, changing the physical parameters of the shoe surface to reduce wear while maintaining protective function
Solution Approach 2:
The patent uses composite material structure combining the base shoe material with a specialized wear-resistant coating layer, creating a multi-layer composite that provides both structural support and enhanced wear resistance
2Productivity
If the plow blade contacts the road surface directly, then effective snow removal is achieved, but the hard and rough road surface causes damage to the plow blade over time
Solution Approach 1:
The patent modifies the surface parameters of the plow blade through application of a hard wear-resistant coating, changing the hardness and abrasion resistance properties to withstand road surface contact
Solution Approach 2:
The wear-resistant coating serves as a protective layer applied in advance to the plow blade, cushioning it against damage from road surface contact before actual plowing operations begin
3Productivity
If the plow blade is held in contact with the road surface by weight and support members, then effective plowing is achieved, but vibration from interaction with rough surface accelerates wear
Solution Approach 1:
The patent changes the vibrational and frictional parameters of the contact surface through the wear-resistant coating, reducing vibration generation and damping existing vibrations to extend component life

AI summary
An exemplary plow includes a moldboard having a wear surface and a blade having a wear surface. A wear resistant coating is applied to at least a portion of at least one of the wear surfaces of the blade and moldboard. The wear resistant coating includes a plurality of scales. Each scale has a leading edge, a trailing edge, a raised portion disposed between the leading edge and the trailing edge, and a peak of the raised portion disposed closer to the trailing edge than the leading edge. The scales of the wear resistant coating are arranged in a plurality of rows, and gaps formed between scales in one row are offset from gaps formed between scales in an adjacent row.
