WHAT CAN WE DO FOR YOU?

Spreitzer offers the trend-setting plasma nitriding technology in the ionic process as a service for you. This surface hardening process in a vacuum using ionized and reactive gases, is particularly characterized by low distortion, wear resistance and dimensional stability. It is mainly used for warpage-sensitive and highly stressed components.

Individual support

Customer-oriented thinking and acting is always in the foreground at Spreitzer. Each customer is served individually. We see ourselves as a service provider and the satisfaction of our customers is our top priority. We are specialist in this field and are glad to share our expertise with you on any plasma nitriding issue.

+ Strengths:

  • Our core competence lies in the fast and uncomplicated processing of small quantities, spare parts and sample parts.
  • Your high-quality components are in good hands with us.

Plasma nitriding by the ionic process

The main advantages of plasma nitriding by the ionic process include the improvement of friction and sliding properties, the Creation of corrosion-resistant coatings and the great low warpage. Generally, only finish-machined components are plasma-nitrided which, after this thermochemical heat treatment, require only minor mechanical manufacturing operation such as grinding. This is for the metalworking industry an important economic and technical point of view.

All common steel, cast iron and sintered materials can be used. plasmanitrated. Suitable are unalloyed, as well as low and high alloy steels. We treat all workpieces, also long or geometrically complicated shapes and parts.

PROCESS AND PROCEDURE

1. necessary data for your order:

  • Steel designation / material number
  • Indication of possible pre-treatment of the parts
  • Desired nitriding hardness depth (NHT) in mm
  • Desired surface hardness in HV1
  • Thickness of the compound layer in μm (optional)
  • Possible footprint; in case of partial treatment, the required hardness ranges shall be marked. Areas that are not to be cured can be covered.

2. part preparation for optimal treatment

  • The parts must be delivered metallically bright, without paint, rust and scale.

3. running time

  • For our customers we have two plants in our house as well as further plants outside our house.

TITANIUM NITRIDE IMPLANT

Titanium nitride implantation of cutting tools

This process is used for surface hardening of HSS tools. The treatment is carried out in a special form during the normal hardening process within our plasma nitriding facilities.

  • Increased surface hardness
  • Increased surface density, low coefficient of friction
  • No geometric and dimensional changes to the mold
  • Higher feed per minute (up to 100%)
  • Regrinding possible
  • Cost savings of up to 75% compared to coating processes
