Innovation 1: Ni Alloys Coating Innovation for Sliding Plate Repair (PMUC Year 2023)

On-Site Problem:

Worn and scratched Sliding Plates due to friction, affecting rail expansion and safety.
Typically, these need to be replaced with new ones imported from abroad.

Innovative Solution

Custom Formula Development:

Researched and developed a surface coating material from nickel alloys (Ni Alloys) with high hardness, excellent wear resistance, and pressure tolerance.

Advanced Coating Process:

Uses High-Velocity Oxygen Fuel (HVOF) technology to create a coating that tightly adheres to the original part, has low porosity, and superior mechanical properties.

Laboratory Test Results

2X Harder: Drastically improves scratch and wear resistance.
10X More Corrosion Resistant: Ultra-low 3.73 µm/year rate for long-term protection.
Smoother & More Durable: Lower friction coefficient and >50 MPa adhesion strength.
Microstructurally Sound: Dense, low-porosity layer with no phase change, proven by SEM.

Petty Patent registration No.2403003501

Real-World Application

Repaired and installed the Sliding Plates at Lamphun Railway Station (15 January 2025)
Quality controlled and approved by SRT officers.

Completed Installation

Day 1 Installation (15/01/2025)

After Installation (15/01/2026)

Real-World Pilot Project:Used to repair Sliding Plates at Lamphun Railway Station for almost 1 year. Results showed no visible wear and the plates could bear loads according to railway standards.

Value Created: Reduces maintenance cost per piece by 90% compared to importing new parts.
