To investigate the effect of micro-blasting process and plasma nitriding process on TiCN coated D3 cold work tool steel and study the effect on Mechanical properties of D3 tool steel using Tension, Compression Test and tribological properties using Pin-on disc friction and wear monitor and analyze the results.
In this research, the focus is on the application of forming tools and the selection of D3 tool steel, a commonly used material for manufacturing forming dies. The aim is to investigate the impact of two processes, namely microblasting with TiCN coating and plasma nitriding with TiCN coating, on the mechanical and tribological properties of D3 tool steel. The wear resistance and effectiveness of forming tools are often limited due to various factors such as thermal and mechanical fatigue, cracking, erosion, corrosion, abrasive and adhesive wear, and galling. Moreover, the quality of the formed parts' surface influences the replacement and reconditioning of tools. One of the challenges in achieving smooth surfaces is the increased surface roughness and tool wear, particularly adhesive wear and galling. Furthermore, tool wear and galling contribute to elevated contact pressures and unstable friction during the forming process. The wear experienced by a tribological pair can vary depending on factors such as the materials in contact, speed, temperature, applied loads, and surface conditions (e.g., roughness, contact area).
2.1 OBJECTIVES 1) To conduct Tension test on treated D3 tool steel specimens. And find out the effect of surface treatments on Yield strength and Tensile strength of D3 steel 2) To conduct Compression test on treated D3 tool steel specimens. And find out the effect of surface treatments on Compressive strength of D3 steel. 3) To conduct wear test on friction and monitor and study the wear behavior of D3 steel and the effect of Load and sliding distance on wear

1. INTRODUCTION
3.1 Plasma Nitriding
Forming industry is very important part of mechanical industries where surface treated forming tools is not developed yet. The aim of this dissertation is to investigate the performance of forming tool by using micro-blasting with TiCN coating and to investigate the influence of plasma nitriding with TiCN coatings on D3 Tool steel.
Plasma nitriding is a case hardening thermochemical surface heat treatment of steel components to produce nitride layers by diffusing nitrogen to substrate surface, which increase wear, corrosion and fatigue resistance
The D3 tool is an air hardening, high carbon , high chromium tool steel. It displays excellent wear resistance and has good dimensional stability and high compressive strength. The D3 Steel has various applications as follows
Nitriding imparts the following properties to steel: Increased surface hardness: Nitriding significantly increases the surface hardness of steel. It forms a hard layer of nitrides, typically iron nitrides, which can significantly enhance the wear resistance of the material.
Blanking, stamping, and cold forming dies and punches for long runs; lamination dies. Bending, forming, and seaming rolls Cold trimmer dies or rolls Burnishing dies or rolls Drawing dies for bars or wire Lathe centers subject to severe wear

Impact Factor value: 8.226
Improved wear resistance: The nitride layer formed during nitriding offers excellent resistance against abrasion, erosion, and fretting wear. This makes nitrided steel suitable for applications involving sliding or rubbing contact with other surfaces.
