Housing assembly for rotary engine and method of manufacturing thereof

A method of manufacturing a component of a housing defining a rotor cavity for receiving a rotor of a rotary internal combustion engine, the method comprising:

• obtaining a body of the component of the housing, the body having a first face and a second face opposite to the first face, the second face facing away from the rotor cavity, the body made of a first material;
• performing a treatment to the body to increase a wear-resistance of the first material;
• depositing a bonding layer on the second face of the body, the bonding layer including a second material being dissimilar from the first material, the first material being more wear-resistant than the second material, the second material defining an exposed face of the bonding layer facing away from the body;
• and
• completing a shape of the body by bonding a quantity of a third material to the exposed face of the bonding layer.
